Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499856, here are decompositions:

3 + 499853 = 499856
37 + 499819 = 499856
109 + 499747 = 499856
127 + 499729 = 499856
139 + 499717 = 499856
163 + 499693 = 499856
193 + 499663 = 499856
223 + 499633 = 499856

Showing the first eight; more decompositions exist.
