Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679646, here are decompositions:

5 + 8679641 = 8679646
29 + 8679617 = 8679646
89 + 8679557 = 8679646
197 + 8679449 = 8679646
293 + 8679353 = 8679646
467 + 8679179 = 8679646
509 + 8679137 = 8679646
587 + 8679059 = 8679646

Showing the first eight; more decompositions exist.
