Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656528, here are decompositions:

5 + 8656523 = 8656528
11 + 8656517 = 8656528
17 + 8656511 = 8656528
29 + 8656499 = 8656528
47 + 8656481 = 8656528
59 + 8656469 = 8656528
149 + 8656379 = 8656528
359 + 8656169 = 8656528

Showing the first eight; more decompositions exist.
