Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600950, here are decompositions:

67 + 31600883 = 31600950
89 + 31600861 = 31600950
107 + 31600843 = 31600950
127 + 31600823 = 31600950
149 + 31600801 = 31600950
151 + 31600799 = 31600950
167 + 31600783 = 31600950
179 + 31600771 = 31600950

Showing the first eight; more decompositions exist.
