Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22210, here are decompositions:
- 17 + 22193 = 22210
- 53 + 22157 = 22210
- 101 + 22109 = 22210
- 131 + 22079 = 22210
- 137 + 22073 = 22210
- 173 + 22037 = 22210
- 179 + 22031 = 22210
- 197 + 22013 = 22210
Showing the first eight; more decompositions exist.
