Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517928, here are decompositions:

67 + 517861 = 517928
97 + 517831 = 517928
181 + 517747 = 517928
199 + 517729 = 517928
211 + 517717 = 517928
331 + 517597 = 517928
379 + 517549 = 517928
421 + 517507 = 517928

Showing the first eight; more decompositions exist.
