Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512218, here are decompositions:

11 + 512207 = 512218
71 + 512147 = 512218
197 + 512021 = 512218
227 + 511991 = 512218
257 + 511961 = 512218
359 + 511859 = 512218
431 + 511787 = 512218
461 + 511757 = 512218

Showing the first eight; more decompositions exist.
