Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602966, here are decompositions:

7 + 31602959 = 31602966
67 + 31602899 = 31602966
89 + 31602877 = 31602966
103 + 31602863 = 31602966
107 + 31602859 = 31602966
113 + 31602853 = 31602966
163 + 31602803 = 31602966
173 + 31602793 = 31602966

Showing the first eight; more decompositions exist.
