Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30270, here are decompositions:

11 + 30259 = 30270
17 + 30253 = 30270
29 + 30241 = 30270
47 + 30223 = 30270
59 + 30211 = 30270
67 + 30203 = 30270
73 + 30197 = 30270
83 + 30187 = 30270

Showing the first eight; more decompositions exist.
