Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565702, here are decompositions:

31 + 31565671 = 31565702
163 + 31565539 = 31565702
211 + 31565491 = 31565702
229 + 31565473 = 31565702
241 + 31565461 = 31565702
271 + 31565431 = 31565702
349 + 31565353 = 31565702
379 + 31565323 = 31565702

Showing the first eight; more decompositions exist.
