Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672766, here are decompositions:

43 + 8672723 = 8672766
59 + 8672707 = 8672766
79 + 8672687 = 8672766
107 + 8672659 = 8672766
127 + 8672639 = 8672766
227 + 8672539 = 8672766
239 + 8672527 = 8672766
257 + 8672509 = 8672766

Showing the first eight; more decompositions exist.
