Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 262, here are decompositions:
- 5 + 257 = 262
- 11 + 251 = 262
- 23 + 239 = 262
- 29 + 233 = 262
- 71 + 191 = 262
- 83 + 179 = 262
- 89 + 173 = 262
- 113 + 149 = 262
Showing the first eight; more decompositions exist.
