Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31896, here are decompositions:

5 + 31891 = 31896
13 + 31883 = 31896
23 + 31873 = 31896
37 + 31859 = 31896
47 + 31849 = 31896
79 + 31817 = 31896
97 + 31799 = 31896
103 + 31793 = 31896

Showing the first eight; more decompositions exist.
