Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565096, here are decompositions:

19 + 31565077 = 31565096
67 + 31565029 = 31565096
163 + 31564933 = 31565096
223 + 31564873 = 31565096
373 + 31564723 = 31565096
439 + 31564657 = 31565096
457 + 31564639 = 31565096
709 + 31564387 = 31565096

Showing the first eight; more decompositions exist.
