Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672656, here are decompositions:

17 + 8672639 = 8672656
59 + 8672597 = 8672656
137 + 8672519 = 8672656
173 + 8672483 = 8672656
227 + 8672429 = 8672656
233 + 8672423 = 8672656
269 + 8672387 = 8672656
359 + 8672297 = 8672656

Showing the first eight; more decompositions exist.
