Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517738, here are decompositions:

5 + 517733 = 517738
17 + 517721 = 517738
101 + 517637 = 517738
149 + 517589 = 517738
167 + 517571 = 517738
191 + 517547 = 517738
227 + 517511 = 517738
239 + 517499 = 517738

Showing the first eight; more decompositions exist.
