Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610646, here are decompositions:

3 + 8610643 = 8610646
29 + 8610617 = 8610646
47 + 8610599 = 8610646
89 + 8610557 = 8610646
137 + 8610509 = 8610646
167 + 8610479 = 8610646
257 + 8610389 = 8610646
269 + 8610377 = 8610646

Showing the first eight; more decompositions exist.
