Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499918, here are decompositions:

131 + 499787 = 499918
137 + 499781 = 499918
179 + 499739 = 499918
227 + 499691 = 499918
239 + 499679 = 499918
257 + 499661 = 499918
269 + 499649 = 499918
281 + 499637 = 499918

Showing the first eight; more decompositions exist.
