Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516278, here are decompositions:

31 + 516247 = 516278
79 + 516199 = 516278
109 + 516169 = 516278
127 + 516151 = 516278
151 + 516127 = 516278
229 + 516049 = 516278
337 + 515941 = 516278
349 + 515929 = 516278

Showing the first eight; more decompositions exist.
