Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631288, here are decompositions:

5 + 8631283 = 8631288
11 + 8631277 = 8631288
19 + 8631269 = 8631288
37 + 8631251 = 8631288
41 + 8631247 = 8631288
59 + 8631229 = 8631288
89 + 8631199 = 8631288
97 + 8631191 = 8631288

Showing the first eight; more decompositions exist.
