Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679660, here are decompositions:

19 + 8679641 = 8679660
43 + 8679617 = 8679660
53 + 8679607 = 8679660
79 + 8679581 = 8679660
103 + 8679557 = 8679660
109 + 8679551 = 8679660
131 + 8679529 = 8679660
211 + 8679449 = 8679660

Showing the first eight; more decompositions exist.
