Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11856, here are decompositions:
- 17 + 11839 = 11856
- 23 + 11833 = 11856
- 29 + 11827 = 11856
- 43 + 11813 = 11856
- 67 + 11789 = 11856
- 73 + 11783 = 11856
- 79 + 11777 = 11856
- 113 + 11743 = 11856
Showing the first eight; more decompositions exist.
