Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22228, here are decompositions:
- 71 + 22157 = 22228
- 137 + 22091 = 22228
- 149 + 22079 = 22228
- 191 + 22037 = 22228
- 197 + 22031 = 22228
- 251 + 21977 = 22228
- 317 + 21911 = 22228
- 347 + 21881 = 22228
Showing the first eight; more decompositions exist.
