Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12906, here are decompositions:
- 7 + 12899 = 12906
- 13 + 12893 = 12906
- 17 + 12889 = 12906
- 53 + 12853 = 12906
- 83 + 12823 = 12906
- 97 + 12809 = 12906
- 107 + 12799 = 12906
- 149 + 12757 = 12906
Showing the first eight; more decompositions exist.
