Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481448, here are decompositions:

31 + 481417 = 481448
61 + 481387 = 481448
151 + 481297 = 481448
199 + 481249 = 481448
241 + 481207 = 481448
271 + 481177 = 481448
277 + 481171 = 481448
307 + 481141 = 481448

Showing the first eight; more decompositions exist.
