Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2236, here are decompositions:
- 23 + 2213 = 2236
- 29 + 2207 = 2236
- 83 + 2153 = 2236
- 107 + 2129 = 2236
- 137 + 2099 = 2236
- 149 + 2087 = 2236
- 167 + 2069 = 2236
- 173 + 2063 = 2236
Showing the first eight; more decompositions exist.
