Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478448, here are decompositions:

7 + 478441 = 478448
31 + 478417 = 478448
37 + 478411 = 478448
97 + 478351 = 478448
109 + 478339 = 478448
127 + 478321 = 478448
241 + 478207 = 478448
277 + 478171 = 478448

Showing the first eight; more decompositions exist.
