Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 292, here are decompositions:
- 11 + 281 = 292
- 23 + 269 = 292
- 29 + 263 = 292
- 41 + 251 = 292
- 53 + 239 = 292
- 59 + 233 = 292
- 101 + 191 = 292
- 113 + 179 = 292
Showing the first eight; more decompositions exist.
