Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657646, here are decompositions:

7 + 8657639 = 8657646
13 + 8657633 = 8657646
17 + 8657629 = 8657646
79 + 8657567 = 8657646
83 + 8657563 = 8657646
89 + 8657557 = 8657646
113 + 8657533 = 8657646
197 + 8657449 = 8657646

Showing the first eight; more decompositions exist.
