Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 296, here are decompositions:
- 3 + 293 = 296
- 13 + 283 = 296
- 19 + 277 = 296
- 67 + 229 = 296
- 73 + 223 = 296
- 97 + 199 = 296
- 103 + 193 = 296
- 139 + 157 = 296
Showing the first eight; more decompositions exist.
