Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511870, here are decompositions:

3 + 511867 = 511870
11 + 511859 = 511870
59 + 511811 = 511870
83 + 511787 = 511870
113 + 511757 = 511870
167 + 511703 = 511870
179 + 511691 = 511870
239 + 511631 = 511870

Showing the first eight; more decompositions exist.
