Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679730, here are decompositions:

53 + 8679677 = 8679730
89 + 8679641 = 8679730
113 + 8679617 = 8679730
149 + 8679581 = 8679730
173 + 8679557 = 8679730
179 + 8679551 = 8679730
281 + 8679449 = 8679730
383 + 8679347 = 8679730

Showing the first eight; more decompositions exist.
