Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565634, here are decompositions:

31 + 31565603 = 31565634
73 + 31565561 = 31565634
137 + 31565497 = 31565634
173 + 31565461 = 31565634
197 + 31565437 = 31565634
211 + 31565423 = 31565634
223 + 31565411 = 31565634
251 + 31565383 = 31565634

Showing the first eight; more decompositions exist.
