Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712904, here are decompositions:

41 + 8712863 = 8712904
191 + 8712713 = 8712904
227 + 8712677 = 8712904
293 + 8712611 = 8712904
593 + 8712311 = 8712904
617 + 8712287 = 8712904
647 + 8712257 = 8712904
677 + 8712227 = 8712904

Showing the first eight; more decompositions exist.
