Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656518, here are decompositions:

7 + 8656511 = 8656518
19 + 8656499 = 8656518
37 + 8656481 = 8656518
41 + 8656477 = 8656518
107 + 8656411 = 8656518
139 + 8656379 = 8656518
149 + 8656369 = 8656518
151 + 8656367 = 8656518

Showing the first eight; more decompositions exist.
