Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512782, here are decompositions:

3 + 512779 = 512782
41 + 512741 = 512782
71 + 512711 = 512782
173 + 512609 = 512782
191 + 512591 = 512782
239 + 512543 = 512782
251 + 512531 = 512782
353 + 512429 = 512782

Showing the first eight; more decompositions exist.
