Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512402, here are decompositions:

13 + 512389 = 512402
151 + 512251 = 512402
439 + 511963 = 512402
463 + 511939 = 512402
571 + 511831 = 512402
601 + 511801 = 512402
691 + 511711 = 512402
733 + 511669 = 512402

Showing the first eight; more decompositions exist.
