Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640448, here are decompositions:

29 + 8640419 = 8640448
41 + 8640407 = 8640448
197 + 8640251 = 8640448
227 + 8640221 = 8640448
251 + 8640197 = 8640448
389 + 8640059 = 8640448
431 + 8640017 = 8640448
461 + 8639987 = 8640448

Showing the first eight; more decompositions exist.
