Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628660, here are decompositions:

13 + 8628647 = 8628660
17 + 8628643 = 8628660
31 + 8628629 = 8628660
37 + 8628623 = 8628660
59 + 8628601 = 8628660
107 + 8628553 = 8628660
109 + 8628551 = 8628660
113 + 8628547 = 8628660

Showing the first eight; more decompositions exist.
