Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565176, here are decompositions:

3 + 31565173 = 31565176
17 + 31565159 = 31565176
47 + 31565129 = 31565176
59 + 31565117 = 31565176
89 + 31565087 = 31565176
107 + 31565069 = 31565176
197 + 31564979 = 31565176
233 + 31564943 = 31565176

Showing the first eight; more decompositions exist.
