Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516990, here are decompositions:

11 + 516979 = 516990
13 + 516977 = 516990
17 + 516973 = 516990
31 + 516959 = 516990
41 + 516949 = 516990
43 + 516947 = 516990
59 + 516931 = 516990
79 + 516911 = 516990

Showing the first eight; more decompositions exist.
