Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625448, here are decompositions:

17 + 8625431 = 8625448
89 + 8625359 = 8625448
131 + 8625317 = 8625448
137 + 8625311 = 8625448
257 + 8625191 = 8625448
317 + 8625131 = 8625448
389 + 8625059 = 8625448
449 + 8624999 = 8625448

Showing the first eight; more decompositions exist.
