Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659966, here are decompositions:

17 + 8659949 = 8659966
53 + 8659913 = 8659966
173 + 8659793 = 8659966
197 + 8659769 = 8659966
503 + 8659463 = 8659966
509 + 8659457 = 8659966
677 + 8659289 = 8659966
743 + 8659223 = 8659966

Showing the first eight; more decompositions exist.
