Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608108, here are decompositions:

17 + 31608091 = 31608108
41 + 31608067 = 31608108
47 + 31608061 = 31608108
61 + 31608047 = 31608108
67 + 31608041 = 31608108
71 + 31608037 = 31608108
79 + 31608029 = 31608108
137 + 31607971 = 31608108

Showing the first eight; more decompositions exist.
