Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516740, here are decompositions:

13 + 516727 = 516740
19 + 516721 = 516740
31 + 516709 = 516740
61 + 516679 = 516740
67 + 516673 = 516740
97 + 516643 = 516740
151 + 516589 = 516740
199 + 516541 = 516740

Showing the first eight; more decompositions exist.
