Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512748, here are decompositions:

7 + 512741 = 512748
31 + 512717 = 512748
37 + 512711 = 512748
107 + 512641 = 512748
127 + 512621 = 512748
139 + 512609 = 512748
151 + 512597 = 512748
157 + 512591 = 512748

Showing the first eight; more decompositions exist.
