Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510494, here are decompositions:

13 + 510481 = 510494
31 + 510463 = 510494
37 + 510457 = 510494
43 + 510451 = 510494
163 + 510331 = 510494
223 + 510271 = 510494
241 + 510253 = 510494
277 + 510217 = 510494

Showing the first eight; more decompositions exist.
