Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631482, here are decompositions:

3 + 8631479 = 8631482
31 + 8631451 = 8631482
103 + 8631379 = 8631482
109 + 8631373 = 8631482
151 + 8631331 = 8631482
163 + 8631319 = 8631482
199 + 8631283 = 8631482
283 + 8631199 = 8631482

Showing the first eight; more decompositions exist.
