Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565464, here are decompositions:

3 + 31565461 = 31565464
41 + 31565423 = 31565464
53 + 31565411 = 31565464
113 + 31565351 = 31565464
167 + 31565297 = 31565464
173 + 31565291 = 31565464
233 + 31565231 = 31565464
257 + 31565207 = 31565464

Showing the first eight; more decompositions exist.
