Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649556, here are decompositions:

23 + 8649533 = 8649556
89 + 8649467 = 8649556
137 + 8649419 = 8649556
173 + 8649383 = 8649556
233 + 8649323 = 8649556
239 + 8649317 = 8649556
257 + 8649299 = 8649556
263 + 8649293 = 8649556

Showing the first eight; more decompositions exist.
