Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499720, here are decompositions:

3 + 499717 = 499720
29 + 499691 = 499720
41 + 499679 = 499720
47 + 499673 = 499720
59 + 499661 = 499720
71 + 499649 = 499720
83 + 499637 = 499720
113 + 499607 = 499720

Showing the first eight; more decompositions exist.
