Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499828, here are decompositions:

41 + 499787 = 499828
47 + 499781 = 499828
89 + 499739 = 499828
137 + 499691 = 499828
149 + 499679 = 499828
167 + 499661 = 499828
179 + 499649 = 499828
191 + 499637 = 499828

Showing the first eight; more decompositions exist.
