Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 298, here are decompositions:
- 5 + 293 = 298
- 17 + 281 = 298
- 29 + 269 = 298
- 41 + 257 = 298
- 47 + 251 = 298
- 59 + 239 = 298
- 71 + 227 = 298
- 101 + 197 = 298
Showing the first eight; more decompositions exist.
