Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656522, here are decompositions:

5 + 8656517 = 8656522
11 + 8656511 = 8656522
23 + 8656499 = 8656522
29 + 8656493 = 8656522
41 + 8656481 = 8656522
53 + 8656469 = 8656522
59 + 8656463 = 8656522
89 + 8656433 = 8656522

Showing the first eight; more decompositions exist.
