Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12782, here are decompositions:
- 19 + 12763 = 12782
- 43 + 12739 = 12782
- 61 + 12721 = 12782
- 79 + 12703 = 12782
- 163 + 12619 = 12782
- 181 + 12601 = 12782
- 193 + 12589 = 12782
- 199 + 12583 = 12782
Showing the first eight; more decompositions exist.
