Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20384, here are decompositions:

31 + 20353 = 20384
37 + 20347 = 20384
43 + 20341 = 20384
61 + 20323 = 20384
97 + 20287 = 20384
151 + 20233 = 20384
211 + 20173 = 20384
223 + 20161 = 20384

Showing the first eight; more decompositions exist.
