Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512420, here are decompositions:

31 + 512389 = 512420
67 + 512353 = 512420
109 + 512311 = 512420
151 + 512269 = 512420
283 + 512137 = 512420
373 + 512047 = 512420
409 + 512011 = 512420
457 + 511963 = 512420

Showing the first eight; more decompositions exist.
