Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491016, here are decompositions:

13 + 491003 = 491016
23 + 490993 = 491016
47 + 490969 = 491016
59 + 490957 = 491016
67 + 490949 = 491016
79 + 490937 = 491016
89 + 490927 = 491016
103 + 490913 = 491016

Showing the first eight; more decompositions exist.
