Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11866, here are decompositions:
- 3 + 11863 = 11866
- 53 + 11813 = 11866
- 59 + 11807 = 11866
- 83 + 11783 = 11866
- 89 + 11777 = 11866
- 149 + 11717 = 11866
- 167 + 11699 = 11866
- 233 + 11633 = 11866
Showing the first eight; more decompositions exist.
