Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512458, here are decompositions:

29 + 512429 = 512458
137 + 512321 = 512458
251 + 512207 = 512458
311 + 512147 = 512458
449 + 512009 = 512458
461 + 511997 = 512458
467 + 511991 = 512458
599 + 511859 = 512458

Showing the first eight; more decompositions exist.
