Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499888, here are decompositions:

5 + 499883 = 499888
101 + 499787 = 499888
107 + 499781 = 499888
149 + 499739 = 499888
197 + 499691 = 499888
227 + 499661 = 499888
239 + 499649 = 499888
251 + 499637 = 499888

Showing the first eight; more decompositions exist.
