Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512800, here are decompositions:

3 + 512797 = 512800
53 + 512747 = 512800
59 + 512741 = 512800
83 + 512717 = 512800
89 + 512711 = 512800
137 + 512663 = 512800
179 + 512621 = 512800
191 + 512609 = 512800

Showing the first eight; more decompositions exist.
