Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516680, here are decompositions:

7 + 516673 = 516680
37 + 516643 = 516680
61 + 516619 = 516680
139 + 516541 = 516680
163 + 516517 = 516680
181 + 516499 = 516680
211 + 516469 = 516680
223 + 516457 = 516680

Showing the first eight; more decompositions exist.
