Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679666, here are decompositions:

59 + 8679607 = 8679666
109 + 8679557 = 8679666
137 + 8679529 = 8679666
139 + 8679527 = 8679666
167 + 8679499 = 8679666
239 + 8679427 = 8679666
269 + 8679397 = 8679666
293 + 8679373 = 8679666

Showing the first eight; more decompositions exist.
