Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670646, here are decompositions:

113 + 8670533 = 8670646
137 + 8670509 = 8670646
239 + 8670407 = 8670646
293 + 8670353 = 8670646
389 + 8670257 = 8670646
449 + 8670197 = 8670646
557 + 8670089 = 8670646
617 + 8670029 = 8670646

Showing the first eight; more decompositions exist.
