Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 282, here are decompositions:
- 5 + 277 = 282
- 11 + 271 = 282
- 13 + 269 = 282
- 19 + 263 = 282
- 31 + 251 = 282
- 41 + 241 = 282
- 43 + 239 = 282
- 53 + 229 = 282
Showing the first eight; more decompositions exist.
