Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649568, here are decompositions:

47 + 8649521 = 8649568
89 + 8649479 = 8649568
101 + 8649467 = 8649568
149 + 8649419 = 8649568
197 + 8649371 = 8649568
251 + 8649317 = 8649568
269 + 8649299 = 8649568
647 + 8648921 = 8649568

Showing the first eight; more decompositions exist.
