Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516172, here are decompositions:

3 + 516169 = 516172
11 + 516161 = 516172
149 + 516023 = 516172
179 + 515993 = 516172
311 + 515861 = 516172
359 + 515813 = 516172
389 + 515783 = 516172
401 + 515771 = 516172

Showing the first eight; more decompositions exist.
