Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511930, here are decompositions:

71 + 511859 = 511930
137 + 511793 = 511930
173 + 511757 = 511930
227 + 511703 = 511930
239 + 511691 = 511930
347 + 511583 = 511930
389 + 511541 = 511930
443 + 511487 = 511930

Showing the first eight; more decompositions exist.
