Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608706, here are decompositions:

179 + 31608527 = 31608706
257 + 31608449 = 31608706
443 + 31608263 = 31608706
557 + 31608149 = 31608706
599 + 31608107 = 31608706
659 + 31608047 = 31608706
677 + 31608029 = 31608706
797 + 31607909 = 31608706

Showing the first eight; more decompositions exist.
