Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516828, here are decompositions:

7 + 516821 = 516828
17 + 516811 = 516828
71 + 516757 = 516828
101 + 516727 = 516828
107 + 516721 = 516828
127 + 516701 = 516828
139 + 516689 = 516828
149 + 516679 = 516828

Showing the first eight; more decompositions exist.
