Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499690, here are decompositions:

3 + 499687 = 499690
11 + 499679 = 499690
17 + 499673 = 499690
29 + 499661 = 499690
41 + 499649 = 499690
53 + 499637 = 499690
83 + 499607 = 499690
89 + 499601 = 499690

Showing the first eight; more decompositions exist.
