Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30404, here are decompositions:

13 + 30391 = 30404
37 + 30367 = 30404
97 + 30307 = 30404
151 + 30253 = 30404
163 + 30241 = 30404
181 + 30223 = 30404
193 + 30211 = 30404
223 + 30181 = 30404

Showing the first eight; more decompositions exist.
