Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631340, here are decompositions:

71 + 8631269 = 8631340
89 + 8631251 = 8631340
149 + 8631191 = 8631340
173 + 8631167 = 8631340
257 + 8631083 = 8631340
317 + 8631023 = 8631340
479 + 8630861 = 8631340
503 + 8630837 = 8631340

Showing the first eight; more decompositions exist.
