Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608174, here are decompositions:

5 + 31608169 = 31608174
7 + 31608167 = 31608174
11 + 31608163 = 31608174
41 + 31608133 = 31608174
43 + 31608131 = 31608174
67 + 31608107 = 31608174
83 + 31608091 = 31608174
107 + 31608067 = 31608174

Showing the first eight; more decompositions exist.
