Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499168, here are decompositions:

11 + 499157 = 499168
17 + 499151 = 499168
29 + 499139 = 499168
41 + 499127 = 499168
101 + 499067 = 499168
179 + 498989 = 499168
191 + 498977 = 499168
311 + 498857 = 499168

Showing the first eight; more decompositions exist.
