Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631624, here are decompositions:

7 + 8631617 = 8631624
13 + 8631611 = 8631624
107 + 8631517 = 8631624
173 + 8631451 = 8631624
223 + 8631401 = 8631624
233 + 8631391 = 8631624
251 + 8631373 = 8631624
257 + 8631367 = 8631624

Showing the first eight; more decompositions exist.
