Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718448, here are decompositions:

17 + 8718431 = 8718448
29 + 8718419 = 8718448
41 + 8718407 = 8718448
47 + 8718401 = 8718448
71 + 8718377 = 8718448
197 + 8718251 = 8718448
227 + 8718221 = 8718448
251 + 8718197 = 8718448

Showing the first eight; more decompositions exist.
