Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517938, here are decompositions:

7 + 517931 = 517938
11 + 517927 = 517938
19 + 517919 = 517938
37 + 517901 = 517938
61 + 517877 = 517938
107 + 517831 = 517938
191 + 517747 = 517938
199 + 517739 = 517938

Showing the first eight; more decompositions exist.
