Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512538, here are decompositions:

7 + 512531 = 512538
17 + 512521 = 512538
31 + 512507 = 512538
41 + 512497 = 512538
71 + 512467 = 512538
109 + 512429 = 512538
149 + 512389 = 512538
227 + 512311 = 512538

Showing the first eight; more decompositions exist.
