Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22216, here are decompositions:
- 23 + 22193 = 22216
- 59 + 22157 = 22216
- 83 + 22133 = 22216
- 107 + 22109 = 22216
- 137 + 22079 = 22216
- 149 + 22067 = 22216
- 179 + 22037 = 22216
- 239 + 21977 = 22216
Showing the first eight; more decompositions exist.
