Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631330, here are decompositions:

11 + 8631319 = 8631330
23 + 8631307 = 8631330
47 + 8631283 = 8631330
53 + 8631277 = 8631330
61 + 8631269 = 8631330
79 + 8631251 = 8631330
83 + 8631247 = 8631330
101 + 8631229 = 8631330

Showing the first eight; more decompositions exist.
