Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22256, here are decompositions:
- 67 + 22189 = 22256
- 97 + 22159 = 22256
- 103 + 22153 = 22256
- 109 + 22147 = 22256
- 127 + 22129 = 22256
- 163 + 22093 = 22256
- 193 + 22063 = 22256
- 229 + 22027 = 22256
Showing the first eight; more decompositions exist.
