Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679728, here are decompositions:

19 + 8679709 = 8679728
199 + 8679529 = 8679728
229 + 8679499 = 8679728
271 + 8679457 = 8679728
331 + 8679397 = 8679728
349 + 8679379 = 8679728
439 + 8679289 = 8679728
457 + 8679271 = 8679728

Showing the first eight; more decompositions exist.
