Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565934, here are decompositions:

5 + 31565929 = 31565934
17 + 31565917 = 31565934
47 + 31565887 = 31565934
83 + 31565851 = 31565934
131 + 31565803 = 31565934
163 + 31565771 = 31565934
173 + 31565761 = 31565934
233 + 31565701 = 31565934

Showing the first eight; more decompositions exist.
