Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499998, here are decompositions:

19 + 499979 = 499998
29 + 499969 = 499998
41 + 499957 = 499998
71 + 499927 = 499998
101 + 499897 = 499998
179 + 499819 = 499998
197 + 499801 = 499998
211 + 499787 = 499998

Showing the first eight; more decompositions exist.
