Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644448, here are decompositions:

277 + 8644171 = 8644448
367 + 8644081 = 8644448
457 + 8643991 = 8644448
661 + 8643787 = 8644448
691 + 8643757 = 8644448
727 + 8643721 = 8644448
751 + 8643697 = 8644448
829 + 8643619 = 8644448

Showing the first eight; more decompositions exist.
