Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628708, here are decompositions:

31 + 8628677 = 8628708
47 + 8628661 = 8628708
61 + 8628647 = 8628708
79 + 8628629 = 8628708
107 + 8628601 = 8628708
157 + 8628551 = 8628708
227 + 8628481 = 8628708
229 + 8628479 = 8628708

Showing the first eight; more decompositions exist.
