Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510398, here are decompositions:

19 + 510379 = 510398
37 + 510361 = 510398
67 + 510331 = 510398
79 + 510319 = 510398
127 + 510271 = 510398
151 + 510247 = 510398
157 + 510241 = 510398
181 + 510217 = 510398

Showing the first eight; more decompositions exist.
