Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631282, here are decompositions:

5 + 8631277 = 8631282
13 + 8631269 = 8631282
31 + 8631251 = 8631282
53 + 8631229 = 8631282
83 + 8631199 = 8631282
89 + 8631193 = 8631282
131 + 8631151 = 8631282
173 + 8631109 = 8631282

Showing the first eight; more decompositions exist.
