Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600188, here are decompositions:

31 + 31600157 = 31600188
71 + 31600117 = 31600188
89 + 31600099 = 31600188
101 + 31600087 = 31600188
127 + 31600061 = 31600188
131 + 31600057 = 31600188
149 + 31600039 = 31600188
211 + 31599977 = 31600188

Showing the first eight; more decompositions exist.
