Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608204, here are decompositions:

37 + 31608167 = 31608204
41 + 31608163 = 31608204
71 + 31608133 = 31608204
73 + 31608131 = 31608204
97 + 31608107 = 31608204
113 + 31608091 = 31608204
137 + 31608067 = 31608204
157 + 31608047 = 31608204

Showing the first eight; more decompositions exist.
