Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679656, here are decompositions:

127 + 8679529 = 8679656
157 + 8679499 = 8679656
199 + 8679457 = 8679656
229 + 8679427 = 8679656
277 + 8679379 = 8679656
283 + 8679373 = 8679656
367 + 8679289 = 8679656
379 + 8679277 = 8679656

Showing the first eight; more decompositions exist.
