Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11854, here are decompositions:
- 23 + 11831 = 11854
- 41 + 11813 = 11854
- 47 + 11807 = 11854
- 53 + 11801 = 11854
- 71 + 11783 = 11854
- 137 + 11717 = 11854
- 173 + 11681 = 11854
- 197 + 11657 = 11854
Showing the first eight; more decompositions exist.
