Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517986, here are decompositions:

5 + 517981 = 517986
19 + 517967 = 517986
37 + 517949 = 517986
59 + 517927 = 517986
67 + 517919 = 517986
109 + 517877 = 517986
113 + 517873 = 517986
163 + 517823 = 517986

Showing the first eight; more decompositions exist.
