Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679390, here are decompositions:

11 + 8679379 = 8679390
17 + 8679373 = 8679390
37 + 8679353 = 8679390
43 + 8679347 = 8679390
79 + 8679311 = 8679390
101 + 8679289 = 8679390
113 + 8679277 = 8679390
173 + 8679217 = 8679390

Showing the first eight; more decompositions exist.
