Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679678, here are decompositions:

37 + 8679641 = 8679678
61 + 8679617 = 8679678
71 + 8679607 = 8679678
97 + 8679581 = 8679678
127 + 8679551 = 8679678
149 + 8679529 = 8679678
151 + 8679527 = 8679678
179 + 8679499 = 8679678

Showing the first eight; more decompositions exist.
