Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512758, here are decompositions:

11 + 512747 = 512758
17 + 512741 = 512758
41 + 512717 = 512758
47 + 512711 = 512758
101 + 512657 = 512758
137 + 512621 = 512758
149 + 512609 = 512758
167 + 512591 = 512758

Showing the first eight; more decompositions exist.
