Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516690, here are decompositions:

11 + 516679 = 516690
17 + 516673 = 516690
37 + 516653 = 516690
47 + 516643 = 516690
67 + 516623 = 516690
71 + 516619 = 516690
73 + 516617 = 516690
79 + 516611 = 516690

Showing the first eight; more decompositions exist.
