Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516986, here are decompositions:

7 + 516979 = 516986
13 + 516973 = 516986
37 + 516949 = 516986
79 + 516907 = 516986
103 + 516883 = 516986
109 + 516877 = 516986
139 + 516847 = 516986
157 + 516829 = 516986

Showing the first eight; more decompositions exist.
