Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491018, here are decompositions:

61 + 490957 = 491018
67 + 490951 = 491018
97 + 490921 = 491018
127 + 490891 = 491018
181 + 490837 = 491018
277 + 490741 = 491018
439 + 490579 = 491018
499 + 490519 = 491018

Showing the first eight; more decompositions exist.
