Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565732, here are decompositions:

19 + 31565713 = 31565732
31 + 31565701 = 31565732
61 + 31565671 = 31565732
193 + 31565539 = 31565732
241 + 31565491 = 31565732
271 + 31565461 = 31565732
349 + 31565383 = 31565732
379 + 31565353 = 31565732

Showing the first eight; more decompositions exist.
