Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499156, here are decompositions:

5 + 499151 = 499156
17 + 499139 = 499156
23 + 499133 = 499156
29 + 499127 = 499156
89 + 499067 = 499156
167 + 498989 = 499156
179 + 498977 = 499156
233 + 498923 = 499156

Showing the first eight; more decompositions exist.
