Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679438, here are decompositions:

11 + 8679427 = 8679438
41 + 8679397 = 8679438
59 + 8679379 = 8679438
127 + 8679311 = 8679438
149 + 8679289 = 8679438
167 + 8679271 = 8679438
239 + 8679199 = 8679438
359 + 8679079 = 8679438

Showing the first eight; more decompositions exist.
