Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18022, here are decompositions:
- 41 + 17981 = 18022
- 83 + 17939 = 18022
- 101 + 17921 = 18022
- 113 + 17909 = 18022
- 131 + 17891 = 18022
- 233 + 17789 = 18022
- 239 + 17783 = 18022
- 293 + 17729 = 18022
Showing the first eight; more decompositions exist.
