Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565796, here are decompositions:

5 + 31565791 = 31565796
83 + 31565713 = 31565796
103 + 31565693 = 31565796
193 + 31565603 = 31565796
257 + 31565539 = 31565796
359 + 31565437 = 31565796
373 + 31565423 = 31565796
397 + 31565399 = 31565796

Showing the first eight; more decompositions exist.
