Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631532, here are decompositions:

53 + 8631479 = 8631532
131 + 8631401 = 8631532
191 + 8631341 = 8631532
263 + 8631269 = 8631532
281 + 8631251 = 8631532
449 + 8631083 = 8631532
491 + 8631041 = 8631532
509 + 8631023 = 8631532

Showing the first eight; more decompositions exist.
