Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512908, here are decompositions:

5 + 512903 = 512908
17 + 512891 = 512908
59 + 512849 = 512908
89 + 512819 = 512908
167 + 512741 = 512908
191 + 512717 = 512908
197 + 512711 = 512908
251 + 512657 = 512908

Showing the first eight; more decompositions exist.
