Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565476, here are decompositions:

3 + 31565473 = 31565476
53 + 31565423 = 31565476
167 + 31565309 = 31565476
179 + 31565297 = 31565476
197 + 31565279 = 31565476
227 + 31565249 = 31565476
269 + 31565207 = 31565476
317 + 31565159 = 31565476

Showing the first eight; more decompositions exist.
