Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517786, here are decompositions:

47 + 517739 = 517786
53 + 517733 = 517786
149 + 517637 = 517786
167 + 517619 = 517786
173 + 517613 = 517786
197 + 517589 = 517786
233 + 517553 = 517786
239 + 517547 = 517786

Showing the first eight; more decompositions exist.
