Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628656, here are decompositions:

13 + 8628643 = 8628656
103 + 8628553 = 8628656
109 + 8628547 = 8628656
163 + 8628493 = 8628656
193 + 8628463 = 8628656
307 + 8628349 = 8628656
499 + 8628157 = 8628656
607 + 8628049 = 8628656

Showing the first eight; more decompositions exist.
