Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515120, here are decompositions:

31 + 515089 = 515120
79 + 515041 = 515120
181 + 514939 = 515120
337 + 514783 = 515120
373 + 514747 = 515120
379 + 514741 = 515120
409 + 514711 = 515120
439 + 514681 = 515120

Showing the first eight; more decompositions exist.
