Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516228, here are decompositions:

5 + 516223 = 516228
19 + 516209 = 516228
29 + 516199 = 516228
59 + 516169 = 516228
67 + 516161 = 516228
71 + 516157 = 516228
101 + 516127 = 516228
137 + 516091 = 516228

Showing the first eight; more decompositions exist.
