Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82402, here are decompositions:
- 29 + 82373 = 82402
- 41 + 82361 = 82402
- 53 + 82349 = 82402
- 101 + 82301 = 82402
- 179 + 82223 = 82402
- 239 + 82163 = 82402
- 263 + 82139 = 82402
- 389 + 82013 = 82402
Showing the first eight; more decompositions exist.
