Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11786, here are decompositions:
- 3 + 11783 = 11786
- 7 + 11779 = 11786
- 43 + 11743 = 11786
- 67 + 11719 = 11786
- 97 + 11689 = 11786
- 109 + 11677 = 11786
- 193 + 11593 = 11786
- 199 + 11587 = 11786
Showing the first eight; more decompositions exist.
