Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23018, here are decompositions:
- 7 + 23011 = 23018
- 97 + 22921 = 23018
- 157 + 22861 = 23018
- 211 + 22807 = 23018
- 241 + 22777 = 23018
- 277 + 22741 = 23018
- 349 + 22669 = 23018
- 367 + 22651 = 23018
Showing the first eight; more decompositions exist.
