Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22144, here are decompositions:
- 11 + 22133 = 22144
- 53 + 22091 = 22144
- 71 + 22073 = 22144
- 107 + 22037 = 22144
- 113 + 22031 = 22144
- 131 + 22013 = 22144
- 167 + 21977 = 22144
- 233 + 21911 = 22144
Showing the first eight; more decompositions exist.
