Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608162, here are decompositions:

13 + 31608149 = 31608162
29 + 31608133 = 31608162
31 + 31608131 = 31608162
71 + 31608091 = 31608162
101 + 31608061 = 31608162
149 + 31608013 = 31608162
191 + 31607971 = 31608162
193 + 31607969 = 31608162

Showing the first eight; more decompositions exist.
