Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679638, here are decompositions:

31 + 8679607 = 8679638
109 + 8679529 = 8679638
139 + 8679499 = 8679638
181 + 8679457 = 8679638
211 + 8679427 = 8679638
241 + 8679397 = 8679638
349 + 8679289 = 8679638
367 + 8679271 = 8679638

Showing the first eight; more decompositions exist.
