Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724646, here are decompositions:

3 + 8724643 = 8724646
5 + 8724641 = 8724646
149 + 8724497 = 8724646
167 + 8724479 = 8724646
179 + 8724467 = 8724646
269 + 8724377 = 8724646
317 + 8724329 = 8724646
353 + 8724293 = 8724646

Showing the first eight; more decompositions exist.
