Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 236, here are decompositions:
- 3 + 233 = 236
- 7 + 229 = 236
- 13 + 223 = 236
- 37 + 199 = 236
- 43 + 193 = 236
- 73 + 163 = 236
- 79 + 157 = 236
- 97 + 139 = 236
Showing the first eight; more decompositions exist.
