Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516398, here are decompositions:

7 + 516391 = 516398
37 + 516361 = 516398
79 + 516319 = 516398
151 + 516247 = 516398
199 + 516199 = 516398
229 + 516169 = 516398
241 + 516157 = 516398
271 + 516127 = 516398

Showing the first eight; more decompositions exist.
