Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20896, here are decompositions:

17 + 20879 = 20896
23 + 20873 = 20896
47 + 20849 = 20896
89 + 20807 = 20896
107 + 20789 = 20896
137 + 20759 = 20896
149 + 20747 = 20896
179 + 20717 = 20896

Showing the first eight; more decompositions exist.
