Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20996, here are decompositions:

13 + 20983 = 20996
37 + 20959 = 20996
67 + 20929 = 20996
97 + 20899 = 20996
109 + 20887 = 20996
139 + 20857 = 20996
223 + 20773 = 20996
277 + 20719 = 20996

Showing the first eight; more decompositions exist.
