Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679658, here are decompositions:

17 + 8679641 = 8679658
41 + 8679617 = 8679658
101 + 8679557 = 8679658
107 + 8679551 = 8679658
131 + 8679527 = 8679658
311 + 8679347 = 8679658
347 + 8679311 = 8679658
479 + 8679179 = 8679658

Showing the first eight; more decompositions exist.
