Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30306, here are decompositions:

13 + 30293 = 30306
37 + 30269 = 30306
47 + 30259 = 30306
53 + 30253 = 30306
83 + 30223 = 30306
103 + 30203 = 30306
109 + 30197 = 30306
137 + 30169 = 30306

Showing the first eight; more decompositions exist.
