Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516188, here are decompositions:

19 + 516169 = 516188
31 + 516157 = 516188
37 + 516151 = 516188
61 + 516127 = 516188
97 + 516091 = 516188
139 + 516049 = 516188
271 + 515917 = 516188
331 + 515857 = 516188

Showing the first eight; more decompositions exist.
