Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679566, here are decompositions:

37 + 8679529 = 8679566
67 + 8679499 = 8679566
109 + 8679457 = 8679566
139 + 8679427 = 8679566
193 + 8679373 = 8679566
277 + 8679289 = 8679566
349 + 8679217 = 8679566
367 + 8679199 = 8679566

Showing the first eight; more decompositions exist.
