Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608234, here are decompositions:

17 + 31608217 = 31608234
67 + 31608167 = 31608234
71 + 31608163 = 31608234
101 + 31608133 = 31608234
103 + 31608131 = 31608234
127 + 31608107 = 31608234
167 + 31608067 = 31608234
173 + 31608061 = 31608234

Showing the first eight; more decompositions exist.
