Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 276, here are decompositions:
- 5 + 271 = 276
- 7 + 269 = 276
- 13 + 263 = 276
- 19 + 257 = 276
- 37 + 239 = 276
- 43 + 233 = 276
- 47 + 229 = 276
- 53 + 223 = 276
Showing the first eight; more decompositions exist.
