Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565344, here are decompositions:

47 + 31565297 = 31565344
53 + 31565291 = 31565344
113 + 31565231 = 31565344
137 + 31565207 = 31565344
227 + 31565117 = 31565344
257 + 31565087 = 31565344
353 + 31564991 = 31565344
401 + 31564943 = 31565344

Showing the first eight; more decompositions exist.
