Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631086, here are decompositions:

3 + 8631083 = 8631086
103 + 8630983 = 8631086
157 + 8630929 = 8631086
229 + 8630857 = 8631086
307 + 8630779 = 8631086
337 + 8630749 = 8631086
349 + 8630737 = 8631086
433 + 8630653 = 8631086

Showing the first eight; more decompositions exist.
