Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491454, here are decompositions:

31 + 491423 = 491454
37 + 491417 = 491454
83 + 491371 = 491454
97 + 491357 = 491454
101 + 491353 = 491454
113 + 491341 = 491454
127 + 491327 = 491454
157 + 491297 = 491454

Showing the first eight; more decompositions exist.
