Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517916, here are decompositions:

43 + 517873 = 517916
199 + 517717 = 517916
277 + 517639 = 517916
307 + 517609 = 517916
313 + 517603 = 517916
367 + 517549 = 517916
409 + 517507 = 517916
457 + 517459 = 517916

Showing the first eight; more decompositions exist.
