Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80806, here are decompositions:
- 3 + 80803 = 80806
- 17 + 80789 = 80806
- 23 + 80783 = 80806
- 29 + 80777 = 80806
- 59 + 80747 = 80806
- 137 + 80669 = 80806
- 149 + 80657 = 80806
- 179 + 80627 = 80806
Showing the first eight; more decompositions exist.
