Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712646, here are decompositions:

17 + 8712629 = 8712646
113 + 8712533 = 8712646
149 + 8712497 = 8712646
353 + 8712293 = 8712646
359 + 8712287 = 8712646
389 + 8712257 = 8712646
419 + 8712227 = 8712646
479 + 8712167 = 8712646

Showing the first eight; more decompositions exist.
