Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516242, here are decompositions:

19 + 516223 = 516242
43 + 516199 = 516242
73 + 516169 = 516242
79 + 516163 = 516242
151 + 516091 = 516242
193 + 516049 = 516242
313 + 515929 = 516242
439 + 515803 = 516242

Showing the first eight; more decompositions exist.
