Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510740, here are decompositions:

31 + 510709 = 510740
127 + 510613 = 510740
151 + 510589 = 510740
157 + 510583 = 510740
211 + 510529 = 510740
277 + 510463 = 510740
283 + 510457 = 510740
337 + 510403 = 510740

Showing the first eight; more decompositions exist.
