Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82404, here are decompositions:
- 11 + 82393 = 82404
- 17 + 82387 = 82404
- 31 + 82373 = 82404
- 43 + 82361 = 82404
- 53 + 82351 = 82404
- 97 + 82307 = 82404
- 103 + 82301 = 82404
- 137 + 82267 = 82404
Showing the first eight; more decompositions exist.
