Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512764, here are decompositions:

3 + 512761 = 512764
17 + 512747 = 512764
23 + 512741 = 512764
47 + 512717 = 512764
53 + 512711 = 512764
101 + 512663 = 512764
107 + 512657 = 512764
167 + 512597 = 512764

Showing the first eight; more decompositions exist.
