Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631432, here are decompositions:

31 + 8631401 = 8631432
41 + 8631391 = 8631432
53 + 8631379 = 8631432
59 + 8631373 = 8631432
101 + 8631331 = 8631432
113 + 8631319 = 8631432
149 + 8631283 = 8631432
163 + 8631269 = 8631432

Showing the first eight; more decompositions exist.
