Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22240, here are decompositions:
- 11 + 22229 = 22240
- 47 + 22193 = 22240
- 83 + 22157 = 22240
- 107 + 22133 = 22240
- 131 + 22109 = 22240
- 149 + 22091 = 22240
- 167 + 22073 = 22240
- 173 + 22067 = 22240
Showing the first eight; more decompositions exist.
