Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509120, here are decompositions:

19 + 509101 = 509120
67 + 509053 = 509120
97 + 509023 = 509120
151 + 508969 = 509120
163 + 508957 = 509120
211 + 508909 = 509120
331 + 508789 = 509120
349 + 508771 = 509120

Showing the first eight; more decompositions exist.
