Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22168, here are decompositions:
- 11 + 22157 = 22168
- 59 + 22109 = 22168
- 89 + 22079 = 22168
- 101 + 22067 = 22168
- 131 + 22037 = 22168
- 137 + 22031 = 22168
- 191 + 21977 = 22168
- 239 + 21929 = 22168
Showing the first eight; more decompositions exist.
