Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499930, here are decompositions:

3 + 499927 = 499930
47 + 499883 = 499930
149 + 499781 = 499930
191 + 499739 = 499930
239 + 499691 = 499930
251 + 499679 = 499930
257 + 499673 = 499930
269 + 499661 = 499930

Showing the first eight; more decompositions exist.
