Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679684, here are decompositions:

7 + 8679677 = 8679684
43 + 8679641 = 8679684
67 + 8679617 = 8679684
103 + 8679581 = 8679684
127 + 8679557 = 8679684
157 + 8679527 = 8679684
227 + 8679457 = 8679684
257 + 8679427 = 8679684

Showing the first eight; more decompositions exist.
