Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649448, here are decompositions:

29 + 8649419 = 8649448
131 + 8649317 = 8649448
149 + 8649299 = 8649448
251 + 8649197 = 8649448
257 + 8649191 = 8649448
419 + 8649029 = 8649448
569 + 8648879 = 8649448
617 + 8648831 = 8649448

Showing the first eight; more decompositions exist.
