Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517850, here are decompositions:

19 + 517831 = 517850
103 + 517747 = 517850
139 + 517711 = 517850
211 + 517639 = 517850
241 + 517609 = 517850
337 + 517513 = 517850
349 + 517501 = 517850
379 + 517471 = 517850

Showing the first eight; more decompositions exist.
