Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516842, here are decompositions:

3 + 516839 = 516842
13 + 516829 = 516842
31 + 516811 = 516842
163 + 516679 = 516842
199 + 516643 = 516842
223 + 516619 = 516842
349 + 516493 = 516842
373 + 516469 = 516842

Showing the first eight; more decompositions exist.
