Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510530, here are decompositions:

67 + 510463 = 510530
73 + 510457 = 510530
79 + 510451 = 510530
127 + 510403 = 510530
151 + 510379 = 510530
199 + 510331 = 510530
211 + 510319 = 510530
277 + 510253 = 510530

Showing the first eight; more decompositions exist.
