Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30288, here are decompositions:

17 + 30271 = 30288
19 + 30269 = 30288
29 + 30259 = 30288
47 + 30241 = 30288
101 + 30187 = 30288
107 + 30181 = 30288
127 + 30161 = 30288
149 + 30139 = 30288

Showing the first eight; more decompositions exist.
