Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679986, here are decompositions:

13 + 8679973 = 8679986
43 + 8679943 = 8679986
103 + 8679883 = 8679986
277 + 8679709 = 8679986
379 + 8679607 = 8679986
457 + 8679529 = 8679986
487 + 8679499 = 8679986
607 + 8679379 = 8679986

Showing the first eight; more decompositions exist.
