Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631312, here are decompositions:

5 + 8631307 = 8631312
29 + 8631283 = 8631312
43 + 8631269 = 8631312
61 + 8631251 = 8631312
83 + 8631229 = 8631312
113 + 8631199 = 8631312
229 + 8631083 = 8631312
271 + 8631041 = 8631312

Showing the first eight; more decompositions exist.
