Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706646, here are decompositions:

59 + 8706587 = 8706646
89 + 8706557 = 8706646
149 + 8706497 = 8706646
167 + 8706479 = 8706646
227 + 8706419 = 8706646
233 + 8706413 = 8706646
239 + 8706407 = 8706646
269 + 8706377 = 8706646

Showing the first eight; more decompositions exist.
