Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656656, here are decompositions:

53 + 8656603 = 8656656
67 + 8656589 = 8656656
79 + 8656577 = 8656656
83 + 8656573 = 8656656
109 + 8656547 = 8656656
139 + 8656517 = 8656656
157 + 8656499 = 8656656
163 + 8656493 = 8656656

Showing the first eight; more decompositions exist.
