Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515724, here are decompositions:

23 + 515701 = 515724
31 + 515693 = 515724
37 + 515687 = 515724
43 + 515681 = 515724
47 + 515677 = 515724
61 + 515663 = 515724
71 + 515653 = 515724
73 + 515651 = 515724

Showing the first eight; more decompositions exist.
