Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516878, here are decompositions:

7 + 516871 = 516878
31 + 516847 = 516878
67 + 516811 = 516878
151 + 516727 = 516878
157 + 516721 = 516878
199 + 516679 = 516878
337 + 516541 = 516878
379 + 516499 = 516878

Showing the first eight; more decompositions exist.
