Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12746, here are decompositions:
- 3 + 12743 = 12746
- 7 + 12739 = 12746
- 43 + 12703 = 12746
- 109 + 12637 = 12746
- 127 + 12619 = 12746
- 157 + 12589 = 12746
- 163 + 12583 = 12746
- 193 + 12553 = 12746
Showing the first eight; more decompositions exist.
