Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608198, here are decompositions:

29 + 31608169 = 31608198
31 + 31608167 = 31608198
67 + 31608131 = 31608198
107 + 31608091 = 31608198
131 + 31608067 = 31608198
137 + 31608061 = 31608198
151 + 31608047 = 31608198
157 + 31608041 = 31608198

Showing the first eight; more decompositions exist.
