Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565326, here are decompositions:

3 + 31565323 = 31565326
17 + 31565309 = 31565326
29 + 31565297 = 31565326
47 + 31565279 = 31565326
167 + 31565159 = 31565326
197 + 31565129 = 31565326
239 + 31565087 = 31565326
257 + 31565069 = 31565326

Showing the first eight; more decompositions exist.
