Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499744, here are decompositions:

5 + 499739 = 499744
53 + 499691 = 499744
71 + 499673 = 499744
83 + 499661 = 499744
107 + 499637 = 499744
137 + 499607 = 499744
173 + 499571 = 499744
251 + 499493 = 499744

Showing the first eight; more decompositions exist.
