Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512320, here are decompositions:

71 + 512249 = 512320
113 + 512207 = 512320
173 + 512147 = 512320
227 + 512093 = 512320
311 + 512009 = 512320
359 + 511961 = 512320
461 + 511859 = 512320
509 + 511811 = 512320

Showing the first eight; more decompositions exist.
