Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509216, here are decompositions:

13 + 509203 = 509216
67 + 509149 = 509216
79 + 509137 = 509216
163 + 509053 = 509216
193 + 509023 = 509216
229 + 508987 = 509216
307 + 508909 = 509216
313 + 508903 = 509216

Showing the first eight; more decompositions exist.
