Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609728, here are decompositions:

41 + 8609687 = 8609728
59 + 8609669 = 8609728
89 + 8609639 = 8609728
107 + 8609621 = 8609728
131 + 8609597 = 8609728
137 + 8609591 = 8609728
227 + 8609501 = 8609728
251 + 8609477 = 8609728

Showing the first eight; more decompositions exist.
