Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21796, here are decompositions:

23 + 21773 = 21796
29 + 21767 = 21796
59 + 21737 = 21796
83 + 21713 = 21796
113 + 21683 = 21796
149 + 21647 = 21796
179 + 21617 = 21796
197 + 21599 = 21796

Showing the first eight; more decompositions exist.
