Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80384, here are decompositions:

37 + 80347 = 80384
43 + 80341 = 80384
67 + 80317 = 80384
97 + 80287 = 80384
151 + 80233 = 80384
163 + 80221 = 80384
193 + 80191 = 80384
211 + 80173 = 80384

Showing the first eight; more decompositions exist.
