Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679828, here are decompositions:

37 + 8679791 = 8679828
61 + 8679767 = 8679828
89 + 8679739 = 8679828
151 + 8679677 = 8679828
211 + 8679617 = 8679828
271 + 8679557 = 8679828
277 + 8679551 = 8679828
379 + 8679449 = 8679828

Showing the first eight; more decompositions exist.
