Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679816, here are decompositions:

73 + 8679743 = 8679816
107 + 8679709 = 8679816
139 + 8679677 = 8679816
199 + 8679617 = 8679816
317 + 8679499 = 8679816
359 + 8679457 = 8679816
367 + 8679449 = 8679816
389 + 8679427 = 8679816

Showing the first eight; more decompositions exist.
