Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512530, here are decompositions:

23 + 512507 = 512530
101 + 512429 = 512530
197 + 512333 = 512530
281 + 512249 = 512530
383 + 512147 = 512530
509 + 512021 = 512530
521 + 512009 = 512530
569 + 511961 = 512530

Showing the first eight; more decompositions exist.
