Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647966, here are decompositions:

3 + 8647963 = 8647966
17 + 8647949 = 8647966
29 + 8647937 = 8647966
53 + 8647913 = 8647966
149 + 8647817 = 8647966
227 + 8647739 = 8647966
269 + 8647697 = 8647966
557 + 8647409 = 8647966

Showing the first eight; more decompositions exist.
