TITLE: Is there a maximal prime number not being a sum of consecutive primes?
QUESTION [5 upvotes]: Let $\mathcal S=\{p\in\mathbb P|\exists m,n\in\mathbb Z_+:p=p_n+\cdots+p_{n+m}\}$. For "small" primes, not much greater than one million, it seems that about half of the primes belong to $\mathcal S$. But the greater primes the more combinations of consecutive primes available.
There are $\pi(p)$ primes less than or equal to $p$ and the number of available prime sequences is 
$1\cdot\pi(p)+2\cdot(\pi(p)-1)+3(\pi(p)-2)+\cdots+(\pi(p)-1)\cdot 2=$
$\displaystyle\frac{\pi(p)^3+3\pi(p)^2+4\pi(p)}{6}$
(If I calculated it right).
I suppose it's possible to use the Prime Number Theorem to estimate the probability of $p\in\mathcal S$, but I'm pretty sure that I would mess it up.
My questions are:

Does $P(p\in\mathcal S)\to 1$ as $p\to\infty$?
  Can it be proved that there is a maximal prime number not being a sum of consecutive primes?

See also How often is a sum of $k$ consecutive primes also prime? which is a similar but not an equivalent question.


This is what I got so far. It doesn't support my intuition, but I will let it run up to $10,000,000$ or more.

REPLY [4 votes]: A067377 might help.  I've started a bigger run to plot out behavior.  
mm = Select[
   Union[Flatten[
     Table[Total /@ Partition[Prime[Range[200000]], n, 1], {n, 2, 
       1000}]]], PrimeQ];  
Here's the behavior.  Roughly 44% of primes are sums of consecutive primes at that point.  Chaotic.
