Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78832, here are decompositions:
- 23 + 78809 = 78832
- 29 + 78803 = 78832
- 41 + 78791 = 78832
- 53 + 78779 = 78832
- 179 + 78653 = 78832
- 239 + 78593 = 78832
- 263 + 78569 = 78832
- 293 + 78539 = 78832
Showing the first eight; more decompositions exist.
