Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512778, here are decompositions:

11 + 512767 = 512778
17 + 512761 = 512778
31 + 512747 = 512778
37 + 512741 = 512778
61 + 512717 = 512778
67 + 512711 = 512778
107 + 512671 = 512778
137 + 512641 = 512778

Showing the first eight; more decompositions exist.
