Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679628, here are decompositions:

11 + 8679617 = 8679628
47 + 8679581 = 8679628
71 + 8679557 = 8679628
101 + 8679527 = 8679628
179 + 8679449 = 8679628
281 + 8679347 = 8679628
317 + 8679311 = 8679628
449 + 8679179 = 8679628

Showing the first eight; more decompositions exist.
