Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658966, here are decompositions:

5 + 8658961 = 8658966
7 + 8658959 = 8658966
23 + 8658943 = 8658966
47 + 8658919 = 8658966
73 + 8658893 = 8658966
79 + 8658887 = 8658966
89 + 8658877 = 8658966
97 + 8658869 = 8658966

Showing the first eight; more decompositions exist.
