Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600266, here are decompositions:

7 + 31600259 = 31600266
73 + 31600193 = 31600266
109 + 31600157 = 31600266
149 + 31600117 = 31600266
163 + 31600103 = 31600266
167 + 31600099 = 31600266
179 + 31600087 = 31600266
223 + 31600043 = 31600266

Showing the first eight; more decompositions exist.
