Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11806, here are decompositions:
- 5 + 11801 = 11806
- 17 + 11789 = 11806
- 23 + 11783 = 11806
- 29 + 11777 = 11806
- 89 + 11717 = 11806
- 107 + 11699 = 11806
- 149 + 11657 = 11806
- 173 + 11633 = 11806
Showing the first eight; more decompositions exist.
