Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491514, here are decompositions:

11 + 491503 = 491514
13 + 491501 = 491514
17 + 491497 = 491514
31 + 491483 = 491514
53 + 491461 = 491514
97 + 491417 = 491514
137 + 491377 = 491514
157 + 491357 = 491514

Showing the first eight; more decompositions exist.
