Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28656, here are decompositions:

7 + 28649 = 28656
13 + 28643 = 28656
29 + 28627 = 28656
37 + 28619 = 28656
53 + 28603 = 28656
59 + 28597 = 28656
83 + 28573 = 28656
97 + 28559 = 28656

Showing the first eight; more decompositions exist.
