Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613774, here are decompositions:

17 + 8613757 = 8613774
23 + 8613751 = 8613774
31 + 8613743 = 8613774
41 + 8613733 = 8613774
73 + 8613701 = 8613774
97 + 8613677 = 8613774
151 + 8613623 = 8613774
157 + 8613617 = 8613774

Showing the first eight; more decompositions exist.
