Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679838, here are decompositions:

47 + 8679791 = 8679838
71 + 8679767 = 8679838
197 + 8679641 = 8679838
257 + 8679581 = 8679838
281 + 8679557 = 8679838
311 + 8679527 = 8679838
389 + 8679449 = 8679838
491 + 8679347 = 8679838

Showing the first eight; more decompositions exist.
