Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565224, here are decompositions:

3 + 31565221 = 31565224
17 + 31565207 = 31565224
107 + 31565117 = 31565224
137 + 31565087 = 31565224
167 + 31565057 = 31565224
233 + 31564991 = 31565224
281 + 31564943 = 31565224
443 + 31564781 = 31565224

Showing the first eight; more decompositions exist.
