Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630656, here are decompositions:

3 + 8630653 = 8630656
17 + 8630639 = 8630656
137 + 8630519 = 8630656
173 + 8630483 = 8630656
179 + 8630477 = 8630656
239 + 8630417 = 8630656
269 + 8630387 = 8630656
449 + 8630207 = 8630656

Showing the first eight; more decompositions exist.
