Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516978, here are decompositions:

5 + 516973 = 516978
19 + 516959 = 516978
29 + 516949 = 516978
31 + 516947 = 516978
47 + 516931 = 516978
67 + 516911 = 516978
71 + 516907 = 516978
101 + 516877 = 516978

Showing the first eight; more decompositions exist.
