Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512636, here are decompositions:

43 + 512593 = 512636
67 + 512569 = 512636
139 + 512497 = 512636
193 + 512443 = 512636
283 + 512353 = 512636
349 + 512287 = 512636
367 + 512269 = 512636
499 + 512137 = 512636

Showing the first eight; more decompositions exist.
