Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510490, here are decompositions:

41 + 510449 = 510490
89 + 510401 = 510490
107 + 510383 = 510490
179 + 510311 = 510490
191 + 510299 = 510490
257 + 510233 = 510490
263 + 510227 = 510490
311 + 510179 = 510490

Showing the first eight; more decompositions exist.
