Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511954, here are decompositions:

167 + 511787 = 511954
197 + 511757 = 511954
251 + 511703 = 511954
263 + 511691 = 511954
431 + 511523 = 511954
467 + 511487 = 511954
491 + 511463 = 511954
563 + 511391 = 511954

Showing the first eight; more decompositions exist.
