Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499886, here are decompositions:

3 + 499883 = 499886
7 + 499879 = 499886
67 + 499819 = 499886
139 + 499747 = 499886
157 + 499729 = 499886
193 + 499693 = 499886
199 + 499687 = 499886
223 + 499663 = 499886

Showing the first eight; more decompositions exist.
