Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511966, here are decompositions:

3 + 511963 = 511966
5 + 511961 = 511966
107 + 511859 = 511966
173 + 511793 = 511966
179 + 511787 = 511966
263 + 511703 = 511966
383 + 511583 = 511966
443 + 511523 = 511966

Showing the first eight; more decompositions exist.
