Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608664, here are decompositions:

137 + 31608527 = 31608664
167 + 31608497 = 31608664
401 + 31608263 = 31608664
557 + 31608107 = 31608664
617 + 31608047 = 31608664
743 + 31607921 = 31608664
761 + 31607903 = 31608664
797 + 31607867 = 31608664

Showing the first eight; more decompositions exist.
