Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628684, here are decompositions:

7 + 8628677 = 8628684
23 + 8628661 = 8628684
37 + 8628647 = 8628684
41 + 8628643 = 8628684
61 + 8628623 = 8628684
83 + 8628601 = 8628684
131 + 8628553 = 8628684
137 + 8628547 = 8628684

Showing the first eight; more decompositions exist.
