Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679664, here are decompositions:

23 + 8679641 = 8679664
47 + 8679617 = 8679664
83 + 8679581 = 8679664
107 + 8679557 = 8679664
113 + 8679551 = 8679664
137 + 8679527 = 8679664
311 + 8679353 = 8679664
317 + 8679347 = 8679664

Showing the first eight; more decompositions exist.
