Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12788, here are decompositions:
- 7 + 12781 = 12788
- 31 + 12757 = 12788
- 67 + 12721 = 12788
- 151 + 12637 = 12788
- 199 + 12589 = 12788
- 211 + 12577 = 12788
- 241 + 12547 = 12788
- 271 + 12517 = 12788
Showing the first eight; more decompositions exist.
