Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512938, here are decompositions:

11 + 512927 = 512938
17 + 512921 = 512938
47 + 512891 = 512938
89 + 512849 = 512938
191 + 512747 = 512938
197 + 512741 = 512938
227 + 512711 = 512938
281 + 512657 = 512938

Showing the first eight; more decompositions exist.
