Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509312, here are decompositions:

19 + 509293 = 509312
31 + 509281 = 509312
73 + 509239 = 509312
109 + 509203 = 509312
163 + 509149 = 509312
211 + 509101 = 509312
241 + 509071 = 509312
409 + 508903 = 509312

Showing the first eight; more decompositions exist.
