Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512948, here are decompositions:

19 + 512929 = 512948
31 + 512917 = 512948
127 + 512821 = 512948
151 + 512797 = 512948
181 + 512767 = 512948
277 + 512671 = 512948
307 + 512641 = 512948
367 + 512581 = 512948

Showing the first eight; more decompositions exist.
