Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656564, here are decompositions:

3 + 8656561 = 8656564
17 + 8656547 = 8656564
41 + 8656523 = 8656564
47 + 8656517 = 8656564
53 + 8656511 = 8656564
71 + 8656493 = 8656564
83 + 8656481 = 8656564
101 + 8656463 = 8656564

Showing the first eight; more decompositions exist.
