Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712790, here are decompositions:

11 + 8712779 = 8712790
29 + 8712761 = 8712790
41 + 8712749 = 8712790
89 + 8712701 = 8712790
113 + 8712677 = 8712790
179 + 8712611 = 8712790
257 + 8712533 = 8712790
293 + 8712497 = 8712790

Showing the first eight; more decompositions exist.
