Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607196, here are decompositions:

43 + 31607153 = 31607196
59 + 31607137 = 31607196
109 + 31607087 = 31607196
149 + 31607047 = 31607196
157 + 31607039 = 31607196
199 + 31606997 = 31607196
223 + 31606973 = 31607196
233 + 31606963 = 31607196

Showing the first eight; more decompositions exist.
