Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667966, here are decompositions:

5 + 8667961 = 8667966
17 + 8667949 = 8667966
37 + 8667929 = 8667966
53 + 8667913 = 8667966
59 + 8667907 = 8667966
67 + 8667899 = 8667966
103 + 8667863 = 8667966
137 + 8667829 = 8667966

Showing the first eight; more decompositions exist.
