Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515882, here are decompositions:

43 + 515839 = 515882
79 + 515803 = 515882
109 + 515773 = 515882
181 + 515701 = 515882
229 + 515653 = 515882
271 + 515611 = 515882
571 + 515311 = 515882
691 + 515191 = 515882

Showing the first eight; more decompositions exist.
