Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499990, here are decompositions:

11 + 499979 = 499990
17 + 499973 = 499990
47 + 499943 = 499990
107 + 499883 = 499990
137 + 499853 = 499990
251 + 499739 = 499990
311 + 499679 = 499990
317 + 499673 = 499990

Showing the first eight; more decompositions exist.
