Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631328, here are decompositions:

59 + 8631269 = 8631328
137 + 8631191 = 8631328
311 + 8631017 = 8631328
317 + 8631011 = 8631328
467 + 8630861 = 8631328
491 + 8630837 = 8631328
557 + 8630771 = 8631328
569 + 8630759 = 8631328

Showing the first eight; more decompositions exist.
