Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30752, here are decompositions:
- 103 + 30649 = 30752
- 109 + 30643 = 30752
- 193 + 30559 = 30752
- 199 + 30553 = 30752
- 223 + 30529 = 30752
- 283 + 30469 = 30752
- 349 + 30403 = 30752
- 433 + 30319 = 30752
Showing the first eight; more decompositions exist.
