Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629660, here are decompositions:

23 + 8629637 = 8629660
47 + 8629613 = 8629660
227 + 8629433 = 8629660
251 + 8629409 = 8629660
311 + 8629349 = 8629660
317 + 8629343 = 8629660
419 + 8629241 = 8629660
461 + 8629199 = 8629660

Showing the first eight; more decompositions exist.
