Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649688, here are decompositions:

11 + 8649677 = 8649688
17 + 8649671 = 8649688
59 + 8649629 = 8649688
107 + 8649581 = 8649688
167 + 8649521 = 8649688
197 + 8649491 = 8649688
269 + 8649419 = 8649688
317 + 8649371 = 8649688

Showing the first eight; more decompositions exist.
