Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655966, here are decompositions:

13 + 8655953 = 8655966
29 + 8655937 = 8655966
43 + 8655923 = 8655966
47 + 8655919 = 8655966
83 + 8655883 = 8655966
89 + 8655877 = 8655966
97 + 8655869 = 8655966
107 + 8655859 = 8655966

Showing the first eight; more decompositions exist.
