Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517756, here are decompositions:

17 + 517739 = 517756
23 + 517733 = 517756
137 + 517619 = 517756
167 + 517589 = 517756
179 + 517577 = 517756
257 + 517499 = 517756
269 + 517487 = 517756
353 + 517403 = 517756

Showing the first eight; more decompositions exist.
