Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516558, here are decompositions:

17 + 516541 = 516558
19 + 516539 = 516558
37 + 516521 = 516558
41 + 516517 = 516558
59 + 516499 = 516558
89 + 516469 = 516558
101 + 516457 = 516558
109 + 516449 = 516558

Showing the first eight; more decompositions exist.
