Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679518, here are decompositions:

19 + 8679499 = 8679518
61 + 8679457 = 8679518
139 + 8679379 = 8679518
229 + 8679289 = 8679518
241 + 8679277 = 8679518
409 + 8679109 = 8679518
439 + 8679079 = 8679518
571 + 8678947 = 8679518

Showing the first eight; more decompositions exist.
