Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12812, here are decompositions:
- 3 + 12809 = 12812
- 13 + 12799 = 12812
- 31 + 12781 = 12812
- 73 + 12739 = 12812
- 109 + 12703 = 12812
- 193 + 12619 = 12812
- 199 + 12613 = 12812
- 211 + 12601 = 12812
Showing the first eight; more decompositions exist.
