Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510806, here are decompositions:

3 + 510803 = 510806
13 + 510793 = 510806
97 + 510709 = 510806
193 + 510613 = 510806
223 + 510583 = 510806
277 + 510529 = 510806
349 + 510457 = 510806
487 + 510319 = 510806

Showing the first eight; more decompositions exist.
