Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27280, here are decompositions:

3 + 27277 = 27280
41 + 27239 = 27280
83 + 27197 = 27280
89 + 27191 = 27280
101 + 27179 = 27280
137 + 27143 = 27280
173 + 27107 = 27280
263 + 27017 = 27280

Showing the first eight; more decompositions exist.
