Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517864, here are decompositions:

3 + 517861 = 517864
41 + 517823 = 517864
47 + 517817 = 517864
131 + 517733 = 517864
227 + 517637 = 517864
251 + 517613 = 517864
293 + 517571 = 517864
311 + 517553 = 517864

Showing the first eight; more decompositions exist.
