Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608192, here are decompositions:

23 + 31608169 = 31608192
29 + 31608163 = 31608192
43 + 31608149 = 31608192
59 + 31608133 = 31608192
61 + 31608131 = 31608192
101 + 31608091 = 31608192
131 + 31608061 = 31608192
151 + 31608041 = 31608192

Showing the first eight; more decompositions exist.
