Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567896, here are decompositions:

13 + 31567883 = 31567896
37 + 31567859 = 31567896
47 + 31567849 = 31567896
83 + 31567813 = 31567896
127 + 31567769 = 31567896
167 + 31567729 = 31567896
179 + 31567717 = 31567896
197 + 31567699 = 31567896

Showing the first eight; more decompositions exist.
