Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679966, here are decompositions:

13 + 8679953 = 8679966
23 + 8679943 = 8679966
67 + 8679899 = 8679966
79 + 8679887 = 8679966
83 + 8679883 = 8679966
199 + 8679767 = 8679966
223 + 8679743 = 8679966
227 + 8679739 = 8679966

Showing the first eight; more decompositions exist.
