Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628776, here are decompositions:

3 + 8628773 = 8628776
67 + 8628709 = 8628776
223 + 8628553 = 8628776
229 + 8628547 = 8628776
283 + 8628493 = 8628776
313 + 8628463 = 8628776
619 + 8628157 = 8628776
727 + 8628049 = 8628776

Showing the first eight; more decompositions exist.
