Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516738, here are decompositions:

11 + 516727 = 516738
17 + 516721 = 516738
29 + 516709 = 516738
37 + 516701 = 516738
59 + 516679 = 516738
127 + 516611 = 516738
139 + 516599 = 516738
149 + 516589 = 516738

Showing the first eight; more decompositions exist.
