Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516212, here are decompositions:

3 + 516209 = 516212
13 + 516199 = 516212
19 + 516193 = 516212
43 + 516169 = 516212
61 + 516151 = 516212
163 + 516049 = 516212
271 + 515941 = 516212
283 + 515929 = 516212

Showing the first eight; more decompositions exist.
