Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83440, here are decompositions:
- 3 + 83437 = 83440
- 17 + 83423 = 83440
- 23 + 83417 = 83440
- 41 + 83399 = 83440
- 83 + 83357 = 83440
- 101 + 83339 = 83440
- 167 + 83273 = 83440
- 173 + 83267 = 83440
Showing the first eight; more decompositions exist.
