Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656, here are decompositions:

29 + 8627 = 8656
47 + 8609 = 8656
59 + 8597 = 8656
83 + 8573 = 8656
113 + 8543 = 8656
227 + 8429 = 8656
233 + 8423 = 8656
269 + 8387 = 8656

Showing the first eight; more decompositions exist.
