Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22222, here are decompositions:
- 29 + 22193 = 22222
- 89 + 22133 = 22222
- 113 + 22109 = 22222
- 131 + 22091 = 22222
- 149 + 22073 = 22222
- 191 + 22031 = 22222
- 293 + 21929 = 22222
- 311 + 21911 = 22222
Showing the first eight; more decompositions exist.
