Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656422, here are decompositions:

11 + 8656411 = 8656422
23 + 8656399 = 8656422
29 + 8656393 = 8656422
43 + 8656379 = 8656422
53 + 8656369 = 8656422
59 + 8656363 = 8656422
83 + 8656339 = 8656422
101 + 8656321 = 8656422

Showing the first eight; more decompositions exist.
