Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516998, here are decompositions:

7 + 516991 = 516998
19 + 516979 = 516998
67 + 516931 = 516998
127 + 516871 = 516998
151 + 516847 = 516998
241 + 516757 = 516998
271 + 516727 = 516998
277 + 516721 = 516998

Showing the first eight; more decompositions exist.
