Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565696, here are decompositions:

3 + 31565693 = 31565696
157 + 31565539 = 31565696
199 + 31565497 = 31565696
223 + 31565473 = 31565696
313 + 31565383 = 31565696
373 + 31565323 = 31565696
397 + 31565299 = 31565696
439 + 31565257 = 31565696

Showing the first eight; more decompositions exist.
