Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30658, here are decompositions:
- 101 + 30557 = 30658
- 149 + 30509 = 30658
- 167 + 30491 = 30658
- 191 + 30467 = 30658
- 227 + 30431 = 30658
- 269 + 30389 = 30658
- 311 + 30347 = 30658
- 317 + 30341 = 30658
Showing the first eight; more decompositions exist.
