Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679786, here are decompositions:

19 + 8679767 = 8679786
43 + 8679743 = 8679786
47 + 8679739 = 8679786
109 + 8679677 = 8679786
179 + 8679607 = 8679786
229 + 8679557 = 8679786
257 + 8679529 = 8679786
337 + 8679449 = 8679786

Showing the first eight; more decompositions exist.
