Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515312, here are decompositions:

19 + 515293 = 515312
79 + 515233 = 515312
139 + 515173 = 515312
163 + 515149 = 515312
223 + 515089 = 515312
271 + 515041 = 515312
373 + 514939 = 515312
379 + 514933 = 515312

Showing the first eight; more decompositions exist.
