Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516224, here are decompositions:

31 + 516193 = 516224
61 + 516163 = 516224
67 + 516157 = 516224
73 + 516151 = 516224
97 + 516127 = 516224
283 + 515941 = 516224
307 + 515917 = 516224
337 + 515887 = 516224

Showing the first eight; more decompositions exist.
