Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646966, here are decompositions:

5 + 8646961 = 8646966
17 + 8646949 = 8646966
19 + 8646947 = 8646966
23 + 8646943 = 8646966
37 + 8646929 = 8646966
67 + 8646899 = 8646966
113 + 8646853 = 8646966
149 + 8646817 = 8646966

Showing the first eight; more decompositions exist.
