Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641448, here are decompositions:

19 + 8641429 = 8641448
97 + 8641351 = 8641448
139 + 8641309 = 8641448
199 + 8641249 = 8641448
499 + 8640949 = 8641448
577 + 8640871 = 8641448
631 + 8640817 = 8641448
661 + 8640787 = 8641448

Showing the first eight; more decompositions exist.
