Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516668, here are decompositions:

79 + 516589 = 516668
127 + 516541 = 516668
151 + 516517 = 516668
199 + 516469 = 516668
211 + 516457 = 516668
277 + 516391 = 516668
307 + 516361 = 516668
349 + 516319 = 516668

Showing the first eight; more decompositions exist.
