Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82320, here are decompositions:
- 13 + 82307 = 82320
- 19 + 82301 = 82320
- 41 + 82279 = 82320
- 53 + 82267 = 82320
- 59 + 82261 = 82320
- 79 + 82241 = 82320
- 83 + 82237 = 82320
- 89 + 82231 = 82320
Showing the first eight; more decompositions exist.
