Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628812, here are decompositions:

13 + 8628799 = 8628812
61 + 8628751 = 8628812
103 + 8628709 = 8628812
151 + 8628661 = 8628812
211 + 8628601 = 8628812
331 + 8628481 = 8628812
349 + 8628463 = 8628812
463 + 8628349 = 8628812

Showing the first eight; more decompositions exist.
