Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517918, here are decompositions:

17 + 517901 = 517918
41 + 517877 = 517918
101 + 517817 = 517918
179 + 517739 = 517918
197 + 517721 = 517918
281 + 517637 = 517918
347 + 517571 = 517918
419 + 517499 = 517918

Showing the first eight; more decompositions exist.
