Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2266, here are decompositions:
- 23 + 2243 = 2266
- 29 + 2237 = 2266
- 53 + 2213 = 2266
- 59 + 2207 = 2266
- 113 + 2153 = 2266
- 137 + 2129 = 2266
- 167 + 2099 = 2266
- 179 + 2087 = 2266
Showing the first eight; more decompositions exist.
