Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30318, here are decompositions:
- 5 + 30313 = 30318
- 11 + 30307 = 30318
- 47 + 30271 = 30318
- 59 + 30259 = 30318
- 107 + 30211 = 30318
- 131 + 30187 = 30318
- 137 + 30181 = 30318
- 149 + 30169 = 30318
Showing the first eight; more decompositions exist.
