Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679618, here are decompositions:

11 + 8679607 = 8679618
37 + 8679581 = 8679618
61 + 8679557 = 8679618
67 + 8679551 = 8679618
89 + 8679529 = 8679618
191 + 8679427 = 8679618
239 + 8679379 = 8679618
271 + 8679347 = 8679618

Showing the first eight; more decompositions exist.
