Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512666, here are decompositions:

3 + 512663 = 512666
73 + 512593 = 512666
97 + 512569 = 512666
163 + 512503 = 512666
199 + 512467 = 512666
223 + 512443 = 512666
277 + 512389 = 512666
313 + 512353 = 512666

Showing the first eight; more decompositions exist.
