Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662986, here are decompositions:

23 + 8662963 = 8662986
43 + 8662943 = 8662986
47 + 8662939 = 8662986
97 + 8662889 = 8662986
127 + 8662859 = 8662986
179 + 8662807 = 8662986
239 + 8662747 = 8662986
257 + 8662729 = 8662986

Showing the first eight; more decompositions exist.
