Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608276, here are decompositions:

5 + 31608271 = 31608276
13 + 31608263 = 31608276
59 + 31608217 = 31608276
107 + 31608169 = 31608276
109 + 31608167 = 31608276
113 + 31608163 = 31608276
127 + 31608149 = 31608276
229 + 31608047 = 31608276

Showing the first eight; more decompositions exist.
