Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517804, here are decompositions:

71 + 517733 = 517804
83 + 517721 = 517804
167 + 517637 = 517804
191 + 517613 = 517804
227 + 517577 = 517804
233 + 517571 = 517804
251 + 517553 = 517804
257 + 517547 = 517804

Showing the first eight; more decompositions exist.
