Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656764, here are decompositions:

5 + 8656759 = 8656764
31 + 8656733 = 8656764
37 + 8656727 = 8656764
43 + 8656721 = 8656764
73 + 8656691 = 8656764
97 + 8656667 = 8656764
191 + 8656573 = 8656764
227 + 8656537 = 8656764

Showing the first eight; more decompositions exist.
