Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11906, here are decompositions:
- 3 + 11903 = 11906
- 19 + 11887 = 11906
- 43 + 11863 = 11906
- 67 + 11839 = 11906
- 73 + 11833 = 11906
- 79 + 11827 = 11906
- 127 + 11779 = 11906
- 163 + 11743 = 11906
Showing the first eight; more decompositions exist.
