Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491024, here are decompositions:

31 + 490993 = 491024
67 + 490957 = 491024
73 + 490951 = 491024
97 + 490927 = 491024
103 + 490921 = 491024
241 + 490783 = 491024
283 + 490741 = 491024
397 + 490627 = 491024

Showing the first eight; more decompositions exist.
