Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617448, here are decompositions:

31 + 8617417 = 8617448
67 + 8617381 = 8617448
157 + 8617291 = 8617448
211 + 8617237 = 8617448
241 + 8617207 = 8617448
271 + 8617177 = 8617448
277 + 8617171 = 8617448
457 + 8616991 = 8617448

Showing the first eight; more decompositions exist.
