Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628448, here are decompositions:

5 + 8628443 = 8628448
41 + 8628407 = 8628448
71 + 8628377 = 8628448
89 + 8628359 = 8628448
317 + 8628131 = 8628448
431 + 8628017 = 8628448
461 + 8627987 = 8628448
509 + 8627939 = 8628448

Showing the first eight; more decompositions exist.
