Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515718, here are decompositions:

17 + 515701 = 515718
31 + 515687 = 515718
37 + 515681 = 515718
41 + 515677 = 515718
67 + 515651 = 515718
79 + 515639 = 515718
97 + 515621 = 515718
107 + 515611 = 515718

Showing the first eight; more decompositions exist.
