Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512768, here are decompositions:

7 + 512761 = 512768
97 + 512671 = 512768
127 + 512641 = 512768
199 + 512569 = 512768
271 + 512497 = 512768
349 + 512419 = 512768
379 + 512389 = 512768
457 + 512311 = 512768

Showing the first eight; more decompositions exist.
