Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491448, here are decompositions:

19 + 491429 = 491448
31 + 491417 = 491448
71 + 491377 = 491448
107 + 491341 = 491448
109 + 491339 = 491448
149 + 491299 = 491448
151 + 491297 = 491448
197 + 491251 = 491448

Showing the first eight; more decompositions exist.
