Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628680, here are decompositions:

3 + 8628677 = 8628680
19 + 8628661 = 8628680
37 + 8628643 = 8628680
79 + 8628601 = 8628680
127 + 8628553 = 8628680
199 + 8628481 = 8628680
331 + 8628349 = 8628680
409 + 8628271 = 8628680

Showing the first eight; more decompositions exist.
