Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565296, here are decompositions:

3 + 31565293 = 31565296
5 + 31565291 = 31565296
17 + 31565279 = 31565296
47 + 31565249 = 31565296
89 + 31565207 = 31565296
137 + 31565159 = 31565296
167 + 31565129 = 31565296
179 + 31565117 = 31565296

Showing the first eight; more decompositions exist.
