Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565594, here are decompositions:

97 + 31565497 = 31565594
103 + 31565491 = 31565594
157 + 31565437 = 31565594
163 + 31565431 = 31565594
211 + 31565383 = 31565594
241 + 31565353 = 31565594
271 + 31565323 = 31565594
337 + 31565257 = 31565594

Showing the first eight; more decompositions exist.
