Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608164, here are decompositions:

31 + 31608133 = 31608164
73 + 31608091 = 31608164
97 + 31608067 = 31608164
103 + 31608061 = 31608164
127 + 31608037 = 31608164
151 + 31608013 = 31608164
193 + 31607971 = 31608164
307 + 31607857 = 31608164

Showing the first eight; more decompositions exist.
