Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518756, here are decompositions:

13 + 518743 = 518756
19 + 518737 = 518756
67 + 518689 = 518756
223 + 518533 = 518756
283 + 518473 = 518756
367 + 518389 = 518756
457 + 518299 = 518756
523 + 518233 = 518756

Showing the first eight; more decompositions exist.
