Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631376, here are decompositions:

3 + 8631373 = 8631376
107 + 8631269 = 8631376
293 + 8631083 = 8631376
353 + 8631023 = 8631376
359 + 8631017 = 8631376
563 + 8630813 = 8631376
587 + 8630789 = 8631376
617 + 8630759 = 8631376

Showing the first eight; more decompositions exist.
