Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631308, here are decompositions:

31 + 8631277 = 8631308
61 + 8631247 = 8631308
79 + 8631229 = 8631308
109 + 8631199 = 8631308
157 + 8631151 = 8631308
199 + 8631109 = 8631308
211 + 8631097 = 8631308
271 + 8631037 = 8631308

Showing the first eight; more decompositions exist.
