Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30398, here are decompositions:
- 7 + 30391 = 30398
- 31 + 30367 = 30398
- 79 + 30319 = 30398
- 127 + 30271 = 30398
- 139 + 30259 = 30398
- 157 + 30241 = 30398
- 211 + 30187 = 30398
- 229 + 30169 = 30398
Showing the first eight; more decompositions exist.
