Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628806, here are decompositions:

7 + 8628799 = 8628806
19 + 8628787 = 8628806
79 + 8628727 = 8628806
97 + 8628709 = 8628806
163 + 8628643 = 8628806
313 + 8628493 = 8628806
457 + 8628349 = 8628806
619 + 8628187 = 8628806

Showing the first eight; more decompositions exist.
