Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565652, here are decompositions:

113 + 31565539 = 31565652
179 + 31565473 = 31565652
191 + 31565461 = 31565652
229 + 31565423 = 31565652
241 + 31565411 = 31565652
269 + 31565383 = 31565652
353 + 31565299 = 31565652
359 + 31565293 = 31565652

Showing the first eight; more decompositions exist.
