Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512486, here are decompositions:

19 + 512467 = 512486
43 + 512443 = 512486
67 + 512419 = 512486
97 + 512389 = 512486
199 + 512287 = 512486
349 + 512137 = 512486
439 + 512047 = 512486
523 + 511963 = 512486

Showing the first eight; more decompositions exist.
