But problem 1 is still unsolved despite of the suggestion of the

So remind us - what was problem 1?

This is the problem;

Show that if n>6, then n can be expressed as a sum of distinct
primes.

I'm pretty sure someone pointed out that this follows from Bertrand's
Postulate. Let n be the smallest integer exceeding 6 that can't be
expressed as a sum of distinct primes, then there's a prime p
between n / 2 and n, and then n - p being smaller than n can be
expressed as a sum of distnct primes, etc. With a little touching up,
this should be a proof.

Sorry. There is some hasty in judging your argument.
In fact, it is the same essentially with my first try written in the
top above of this posting.
In your proof, something that I worried can happen.

How do we treat the case n-p less than 6?
