Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516158, here are decompositions:

7 + 516151 = 516158
31 + 516127 = 516158
67 + 516091 = 516158
109 + 516049 = 516158
229 + 515929 = 516158
241 + 515917 = 516158
271 + 515887 = 516158
397 + 515761 = 516158

Showing the first eight; more decompositions exist.
