Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499850, here are decompositions:

31 + 499819 = 499850
103 + 499747 = 499850
139 + 499711 = 499850
157 + 499693 = 499850
163 + 499687 = 499850
181 + 499669 = 499850
229 + 499621 = 499850
331 + 499519 = 499850

Showing the first eight; more decompositions exist.
