Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80420, here are decompositions:

13 + 80407 = 80420
73 + 80347 = 80420
79 + 80341 = 80420
103 + 80317 = 80420
157 + 80263 = 80420
181 + 80239 = 80420
199 + 80221 = 80420
211 + 80209 = 80420

Showing the first eight; more decompositions exist.
