Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30288, here are decompositions:
- 17 + 30271 = 30288
- 19 + 30269 = 30288
- 29 + 30259 = 30288
- 47 + 30241 = 30288
- 101 + 30187 = 30288
- 107 + 30181 = 30288
- 127 + 30161 = 30288
- 149 + 30139 = 30288
Showing the first eight; more decompositions exist.
