Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512384, here are decompositions:

31 + 512353 = 512384
73 + 512311 = 512384
97 + 512287 = 512384
283 + 512101 = 512384
337 + 512047 = 512384
373 + 512011 = 512384
421 + 511963 = 512384
487 + 511897 = 512384

Showing the first eight; more decompositions exist.
