Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40480, here are decompositions:
- 47 + 40433 = 40480
- 53 + 40427 = 40480
- 137 + 40343 = 40480
- 191 + 40289 = 40480
- 197 + 40283 = 40480
- 227 + 40253 = 40480
- 239 + 40241 = 40480
- 311 + 40169 = 40480
Showing the first eight; more decompositions exist.
