Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608214, here are decompositions:

47 + 31608167 = 31608214
83 + 31608131 = 31608214
107 + 31608107 = 31608214
167 + 31608047 = 31608214
173 + 31608041 = 31608214
293 + 31607921 = 31608214
311 + 31607903 = 31608214
317 + 31607897 = 31608214

Showing the first eight; more decompositions exist.
