Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684646, here are decompositions:

17 + 8684629 = 8684646
59 + 8684587 = 8684646
73 + 8684573 = 8684646
109 + 8684537 = 8684646
163 + 8684483 = 8684646
167 + 8684479 = 8684646
227 + 8684419 = 8684646
239 + 8684407 = 8684646

Showing the first eight; more decompositions exist.
