Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607166, here are decompositions:

13 + 31607153 = 31607166
29 + 31607137 = 31607166
79 + 31607087 = 31607166
127 + 31607039 = 31607166
193 + 31606973 = 31607166
223 + 31606943 = 31607166
263 + 31606903 = 31607166
337 + 31606829 = 31607166

Showing the first eight; more decompositions exist.
