Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30308, here are decompositions:

37 + 30271 = 30308
67 + 30241 = 30308
97 + 30211 = 30308
127 + 30181 = 30308
139 + 30169 = 30308
199 + 30109 = 30308
211 + 30097 = 30308
349 + 29959 = 30308

Showing the first eight; more decompositions exist.
