Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491460, here are decompositions:

31 + 491429 = 491460
37 + 491423 = 491460
43 + 491417 = 491460
83 + 491377 = 491460
89 + 491371 = 491460
103 + 491357 = 491460
107 + 491353 = 491460
127 + 491333 = 491460

Showing the first eight; more decompositions exist.
