Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631456, here are decompositions:

5 + 8631451 = 8631456
83 + 8631373 = 8631456
89 + 8631367 = 8631456
137 + 8631319 = 8631456
149 + 8631307 = 8631456
173 + 8631283 = 8631456
179 + 8631277 = 8631456
227 + 8631229 = 8631456

Showing the first eight; more decompositions exist.
