Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631316, here are decompositions:

47 + 8631269 = 8631316
149 + 8631167 = 8631316
233 + 8631083 = 8631316
293 + 8631023 = 8631316
479 + 8630837 = 8631316
503 + 8630813 = 8631316
557 + 8630759 = 8631316
647 + 8630669 = 8631316

Showing the first eight; more decompositions exist.
