Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718966, here are decompositions:

13 + 8718953 = 8718966
17 + 8718949 = 8718966
59 + 8718907 = 8718966
79 + 8718887 = 8718966
89 + 8718877 = 8718966
97 + 8718869 = 8718966
107 + 8718859 = 8718966
127 + 8718839 = 8718966

Showing the first eight; more decompositions exist.
