Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608270, here are decompositions:

7 + 31608263 = 31608270
53 + 31608217 = 31608270
101 + 31608169 = 31608270
103 + 31608167 = 31608270
107 + 31608163 = 31608270
137 + 31608133 = 31608270
139 + 31608131 = 31608270
163 + 31608107 = 31608270

Showing the first eight; more decompositions exist.
