Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83328, here are decompositions:
- 17 + 83311 = 83328
- 29 + 83299 = 83328
- 59 + 83269 = 83328
- 61 + 83267 = 83328
- 71 + 83257 = 83328
- 97 + 83231 = 83328
- 101 + 83227 = 83328
- 107 + 83221 = 83328
Showing the first eight; more decompositions exist.
