If a number is the average (or difference) of two primes, by doubling the number it has a partition of those two primes. So, for example, (7+31)/2=19 becomes 7+31=2∗19. The Goldbach conjecture applies to even numbers only, but the average of two primes applies to every number – even, odd, prime – bigger than 3.
