Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499786, here are decompositions:

5 + 499781 = 499786
47 + 499739 = 499786
107 + 499679 = 499786
113 + 499673 = 499786
137 + 499649 = 499786
149 + 499637 = 499786
179 + 499607 = 499786
227 + 499559 = 499786

Showing the first eight; more decompositions exist.
