Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600164, here are decompositions:

7 + 31600157 = 31600164
31 + 31600133 = 31600164
47 + 31600117 = 31600164
61 + 31600103 = 31600164
103 + 31600061 = 31600164
107 + 31600057 = 31600164
163 + 31600001 = 31600164
223 + 31599941 = 31600164

Showing the first eight; more decompositions exist.
