Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607164, here are decompositions:

11 + 31607153 = 31607164
167 + 31606997 = 31607164
191 + 31606973 = 31607164
233 + 31606931 = 31607164
317 + 31606847 = 31607164
353 + 31606811 = 31607164
461 + 31606703 = 31607164
467 + 31606697 = 31607164

Showing the first eight; more decompositions exist.
