Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649544, here are decompositions:

11 + 8649533 = 8649544
23 + 8649521 = 8649544
53 + 8649491 = 8649544
173 + 8649371 = 8649544
191 + 8649353 = 8649544
227 + 8649317 = 8649544
251 + 8649293 = 8649544
317 + 8649227 = 8649544

Showing the first eight; more decompositions exist.
