Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510842, here are decompositions:

19 + 510823 = 510842
151 + 510691 = 510842
223 + 510619 = 510842
229 + 510613 = 510842
313 + 510529 = 510842
379 + 510463 = 510842
439 + 510403 = 510842
463 + 510379 = 510842

Showing the first eight; more decompositions exist.
