Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649646, here are decompositions:

17 + 8649629 = 8649646
23 + 8649623 = 8649646
113 + 8649533 = 8649646
167 + 8649479 = 8649646
179 + 8649467 = 8649646
227 + 8649419 = 8649646
263 + 8649383 = 8649646
293 + 8649353 = 8649646

Showing the first eight; more decompositions exist.
