Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679864, here are decompositions:

23 + 8679841 = 8679864
73 + 8679791 = 8679864
97 + 8679767 = 8679864
223 + 8679641 = 8679864
257 + 8679607 = 8679864
283 + 8679581 = 8679864
307 + 8679557 = 8679864
313 + 8679551 = 8679864

Showing the first eight; more decompositions exist.
