Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512756, here are decompositions:

43 + 512713 = 512756
73 + 512683 = 512756
163 + 512593 = 512756
313 + 512443 = 512756
337 + 512419 = 512756
367 + 512389 = 512756
487 + 512269 = 512756
619 + 512137 = 512756

Showing the first eight; more decompositions exist.
