Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512836, here are decompositions:

17 + 512819 = 512836
89 + 512747 = 512836
173 + 512663 = 512836
179 + 512657 = 512836
227 + 512609 = 512836
239 + 512597 = 512836
257 + 512579 = 512836
263 + 512573 = 512836

Showing the first eight; more decompositions exist.
