I'd like to offer a heuristic partial answer to a more general question... which relates to some of the discussion in the comments.
Edit: my main point doesn't work, so I will point out the error below - please see the comments. I'll still leave the answer here since the rest of the math seems ok and maybe the idea is helpful somehow. Interesting question! Very nice to think about.
I had to generalize the definition to make my argument work, so that $p$ is a $\textit{survivor of order}$ $m$ if there is a set of primes $\{q_1, \dots, q_m\}$ such that for every $k \le m$, the concatenation of primes
$$ q_k \ q_{k-1} \ \dots \ q_2 \ q_1 \ p $$ is prime.
A $\textit{survivor of order}$ $\infty$ is a prime $p$ along with an infinite set of primes $\{q_1, q_2, q_3, \dots \}$ such that for every $m$, the concatenation of primes
$$ q_m \ q_{m-1} \ \dots \ q_2 \ q_1 \ p $$ is prime.
This is the outline of my argument:
Part 1: Heuristically, it is very likely that for any $k \in \mathbb{N}$, and $n \in \mathbb{N}$ with $n > k$, there is an $n$-digit number which is the concatenation of $k$ many primes.
Part 2: Using the Heuristic Lemma from Part 1, construct a finitely-branching tree $T$ of height $\omega$ (an $\omega$-tree) whose paths correspond to primes which are concatenations of primes. Then use Kőnig's Lemma to show that $T$ must have an infinite path, i.e. a survivor of order $\infty$.
PART 1
A MSE question/answer shows that for every $n \in \mathbb{N}$, there is a prime number with $n$ digits. One of the answers provides more intuition regarding the question:"The number of $n$-digit numbers increases much faster than the density of primes decreases so the number of $n$-digit primes increases rapidly as $n$ increases".
Let $n \in \mathbb{N}$. Define ${Q_n}_1$ to be the number of $n$ digit primes, and define ${Q_n}_2$ to be the number of ways to concatenate primes to make an $n$-digit number.
First, I will estimate ${Q_n}_1$: the number of $n$-digit primes.
Let $n \in \mathbb{N}$. Let $k$ be an $n$-digit number. Then $k < 10^n$, so a conservative estimate of the likelihood that $k$ is prime is
$$ \frac{1}{\ln(10^n)}. $$
Since there are $9^n$ many $n$-digit numbers, there are approximately
$$ \frac{9^n}{\ln(10^n)} $$
many $n$-digit numbers which are prime.
Thus, the estimate for ${Q_n}_1$ is $\frac{9^n}{\ln(10^n)}$.
Here is a table which gives the estimated values versus the real values of numbers of primes for a given length.
\begin{array}{ | c | c | c | c |}
\hline
\mbox{ Digits }& \mbox{ Formula } & \mbox{ Estimate of number of primes } & \mbox{ Actual }\\
\hline
1 & \frac{9}{\ln(10)} & 3.91 & 4 \\
\hline
2 & \frac{9^2}{\ln(10^2)} & 17.59 & 21 \\
\hline
3 & \frac{9^3}{\ln(10^3)} & 105.53 & 142 \\
\hline
4 & \frac{9^4}{\ln(10^4)} & 712.35 & 1061 \\
\hline
\end{array}
Next, I will estimate the number of ways to write an $n$-digit number as a concatenation of primes.
Let $n \in \mathbb{N}$. I'll assume $n$ is odd to make the calculation here slightly simpler. I'm going to estimate the number of ways to write $n$ as a concatenation of two primes, and thus the estimate for the number of ways to write $n$ as a concatenation of more primes will be greater.
For any $n \in \mathbb{N}$ there are $n-1$ many ways to see $n$ as a concatenation of two numbers. For example the 5-digit number 75319 can be seen as: 7-5319, 75-319, 753-19, or 7531-9 (this is a random example, in the work below each part of the concatenation is a prime number).
Let me show how to estimate the number of ways to write a 5-digit number as a concatenation of primes, then the reader can see how I got the estimate for an $n$-digit number.
For a 5-digit number, the first concatenation type is a single digit number followed by a 4-digit number.
There are 4 single digit prime numbers, and there are approximately $\frac{9^4}{\ln(10^4)}$ primes which are 4-digits long.
Thus there are approximately $\frac{4 \cdot 9^4}{\ln(10^4)}$ many 5-digit numbers which are of the first concatenation type.
There are just as many of the concatenation type which is a 4-digit number followed by a single digit number.
For the concatenation type of a 5-digit number which is a 2-digit number followed by a 3-digit number, there are approximately $\frac{9^2 \cdot 9^3}{\ln(10^2) \cdot \ln(10^3)}$ many 5-digit numbers of this concatenation type.
There are the same amount of 5-digit numbers which are of the concatenation type which is a 3-digit number followed by a 2-digit number.
Thus, the total estimate for the number of ways to write a 5-digit number as a concatenation of two primes is
$$ 2 \ \Bigg( \frac{4 \cdot 9^4}{\ln(10^4)} + \frac{9^2 \cdot 9^3}{\ln(10^2) \cdot \ln(10^3)} \Bigg) = 9411.$$
A worked out argument will give the following estimate for the number of ways to write an $n$-digit number as a concatenation of two primes:
$$ 2 \Bigg( \frac{4 \cdot 9^n}{\ln (10^n)} + \frac{9^{n-2} \cdot 9^2}{\ln(10^{n-2})\cdot \ln(10^2) } + \dots + \frac{9^{(n+1)/2} \cdot 9^{(n-1)/2}}{\ln(10^{(n+1)/2}) \cdot \ln(10^{(n-1)/2})} \Bigg) .$$
[This part doesn't really make sense] Thus, the estimate for ${Q_n}_2$ must be greater than the above number. Thus heuristically, ${Q_n}_2 > {Q_n}_1$. That is, the number of ways to write an $n$-digit number as a concatenation of $k$ many primes is greater than the number of $n$-digit primes. So, it is likely that for a given $n$ and $k < n$, there is an $n$-digit number which is both prime and a concatenation of primes.
PART 2
If it is true that for every $n \in \mathbb{N}$ and $k < n$, there is an $n$-digit prime which is a concatenation of $k$ many primes, then I can imagine constructing an $\omega$-tree $T$ whose paths correspond to primes which are concatenations of primes. By Kőnig's lemma $T$ must have an infinite path, and thus there must be a survivor of order $\infty$.
I'd like to expand here to describe $T$:
1) $ t \in T$ if $t$ is prime and a concatenation of primes
2) $s < t$ in $T$ if $t = s^{\cap}q$ where $q \in T$
Let us order $T$ with a lexicographical ordering of the prime "words" created.
First we can see that $T$ is a tree. Then we can see that the tree is finitely branching via the ordering since there are finitely many primes for each number of digits. Finally, $T$ has branches of every height by the Heuristic Lemma of part 1, and thus $T$ has height $\omega$.
If there is no prime survivor of order $\omega$, then $T$ is an $\aleph_0$-Aronszajn tree, which is impossible. Thus, there must be a prime survivor of order $\omega$.
