Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12704, here are decompositions:
- 7 + 12697 = 12704
- 67 + 12637 = 12704
- 103 + 12601 = 12704
- 127 + 12577 = 12704
- 151 + 12553 = 12704
- 157 + 12547 = 12704
- 163 + 12541 = 12704
- 193 + 12511 = 12704
Showing the first eight; more decompositions exist.
