Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510538, here are decompositions:

89 + 510449 = 510538
137 + 510401 = 510538
227 + 510311 = 510538
239 + 510299 = 510538
251 + 510287 = 510538
311 + 510227 = 510538
359 + 510179 = 510538
401 + 510137 = 510538

Showing the first eight; more decompositions exist.
