Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631310, here are decompositions:

3 + 8631307 = 8631310
41 + 8631269 = 8631310
59 + 8631251 = 8631310
227 + 8631083 = 8631310
269 + 8631041 = 8631310
293 + 8631017 = 8631310
449 + 8630861 = 8631310
521 + 8630789 = 8631310

Showing the first eight; more decompositions exist.
