Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512506, here are decompositions:

3 + 512503 = 512506
173 + 512333 = 512506
257 + 512249 = 512506
359 + 512147 = 512506
509 + 511997 = 512506
647 + 511859 = 512506
719 + 511787 = 512506
947 + 511559 = 512506

Showing the first eight; more decompositions exist.
