Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499938, here are decompositions:

11 + 499927 = 499938
41 + 499897 = 499938
59 + 499879 = 499938
137 + 499801 = 499938
151 + 499787 = 499938
157 + 499781 = 499938
191 + 499747 = 499938
199 + 499739 = 499938

Showing the first eight; more decompositions exist.
