Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611306, here are decompositions:

5 + 31611301 = 31611306
7 + 31611299 = 31611306
179 + 31611127 = 31611306
193 + 31611113 = 31611306
239 + 31611067 = 31611306
257 + 31611049 = 31611306
263 + 31611043 = 31611306
269 + 31611037 = 31611306

Showing the first eight; more decompositions exist.
