Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631324, here are decompositions:

5 + 8631319 = 8631324
17 + 8631307 = 8631324
41 + 8631283 = 8631324
47 + 8631277 = 8631324
73 + 8631251 = 8631324
131 + 8631193 = 8631324
157 + 8631167 = 8631324
173 + 8631151 = 8631324

Showing the first eight; more decompositions exist.
