Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609646, here are decompositions:

7 + 8609639 = 8609646
29 + 8609617 = 8609646
37 + 8609609 = 8609646
83 + 8609563 = 8609646
113 + 8609533 = 8609646
163 + 8609483 = 8609646
173 + 8609473 = 8609646
197 + 8609449 = 8609646

Showing the first eight; more decompositions exist.
