Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629966, here are decompositions:

3 + 8629963 = 8629966
5 + 8629961 = 8629966
17 + 8629949 = 8629966
83 + 8629883 = 8629966
227 + 8629739 = 8629966
353 + 8629613 = 8629966
383 + 8629583 = 8629966
557 + 8629409 = 8629966

Showing the first eight; more decompositions exist.
