Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656540, here are decompositions:

3 + 8656537 = 8656540
17 + 8656523 = 8656540
23 + 8656517 = 8656540
29 + 8656511 = 8656540
41 + 8656499 = 8656540
47 + 8656493 = 8656540
59 + 8656481 = 8656540
71 + 8656469 = 8656540

Showing the first eight; more decompositions exist.
