Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499128, here are decompositions:

11 + 499117 = 499128
29 + 499099 = 499128
61 + 499067 = 499128
89 + 499039 = 499128
101 + 499027 = 499128
107 + 499021 = 499128
139 + 498989 = 499128
151 + 498977 = 499128

Showing the first eight; more decompositions exist.
