Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82538, here are decompositions:
- 7 + 82531 = 82538
- 31 + 82507 = 82538
- 67 + 82471 = 82538
- 151 + 82387 = 82538
- 199 + 82339 = 82538
- 271 + 82267 = 82538
- 277 + 82261 = 82538
- 307 + 82231 = 82538
Showing the first eight; more decompositions exist.
