Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517998, here are decompositions:

7 + 517991 = 517998
17 + 517981 = 517998
31 + 517967 = 517998
67 + 517931 = 517998
71 + 517927 = 517998
79 + 517919 = 517998
97 + 517901 = 517998
137 + 517861 = 517998

Showing the first eight; more decompositions exist.
