Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91986, here are decompositions:
- 17 + 91969 = 91986
- 19 + 91967 = 91986
- 29 + 91957 = 91986
- 43 + 91943 = 91986
- 47 + 91939 = 91986
- 113 + 91873 = 91986
- 149 + 91837 = 91986
- 163 + 91823 = 91986
Showing the first eight; more decompositions exist.
