Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515924, here are decompositions:

7 + 515917 = 515924
37 + 515887 = 515924
67 + 515857 = 515924
151 + 515773 = 515924
163 + 515761 = 515924
223 + 515701 = 515924
271 + 515653 = 515924
313 + 515611 = 515924

Showing the first eight; more decompositions exist.
