Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684658, here are decompositions:

29 + 8684629 = 8684658
61 + 8684597 = 8684658
71 + 8684587 = 8684658
137 + 8684521 = 8684658
179 + 8684479 = 8684658
197 + 8684461 = 8684658
239 + 8684419 = 8684658
251 + 8684407 = 8684658

Showing the first eight; more decompositions exist.
