Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628690, here are decompositions:

13 + 8628677 = 8628690
29 + 8628661 = 8628690
43 + 8628647 = 8628690
47 + 8628643 = 8628690
61 + 8628629 = 8628690
67 + 8628623 = 8628690
89 + 8628601 = 8628690
137 + 8628553 = 8628690

Showing the first eight; more decompositions exist.
