Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509072, here are decompositions:

19 + 509053 = 509072
103 + 508969 = 509072
163 + 508909 = 509072
283 + 508789 = 509072
379 + 508693 = 509072
523 + 508549 = 509072
541 + 508531 = 509072
601 + 508471 = 509072

Showing the first eight; more decompositions exist.
