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.
