Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512804, here are decompositions:

7 + 512797 = 512804
37 + 512767 = 512804
43 + 512761 = 512804
163 + 512641 = 512804
211 + 512593 = 512804
223 + 512581 = 512804
283 + 512521 = 512804
307 + 512497 = 512804

Showing the first eight; more decompositions exist.
