Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499812, here are decompositions:

11 + 499801 = 499812
31 + 499781 = 499812
73 + 499739 = 499812
83 + 499729 = 499812
101 + 499711 = 499812
139 + 499673 = 499812
149 + 499663 = 499812
151 + 499661 = 499812

Showing the first eight; more decompositions exist.
