Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30512, here are decompositions:
- 3 + 30509 = 30512
- 19 + 30493 = 30512
- 43 + 30469 = 30512
- 109 + 30403 = 30512
- 193 + 30319 = 30512
- 199 + 30313 = 30512
- 241 + 30271 = 30512
- 271 + 30241 = 30512
Showing the first eight; more decompositions exist.
