Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499740, here are decompositions:

11 + 499729 = 499740
23 + 499717 = 499740
29 + 499711 = 499740
47 + 499693 = 499740
53 + 499687 = 499740
61 + 499679 = 499740
67 + 499673 = 499740
71 + 499669 = 499740

Showing the first eight; more decompositions exist.
