Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656788, here are decompositions:

29 + 8656759 = 8656788
59 + 8656729 = 8656788
61 + 8656727 = 8656788
67 + 8656721 = 8656788
97 + 8656691 = 8656788
199 + 8656589 = 8656788
211 + 8656577 = 8656788
227 + 8656561 = 8656788

Showing the first eight; more decompositions exist.
