Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679188, here are decompositions:

79 + 8679109 = 8679188
109 + 8679079 = 8679188
151 + 8679037 = 8679188
241 + 8678947 = 8679188
337 + 8678851 = 8679188
367 + 8678821 = 8679188
409 + 8678779 = 8679188
439 + 8678749 = 8679188

Showing the first eight; more decompositions exist.
