Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82080, here are decompositions:
- 7 + 82073 = 82080
- 13 + 82067 = 82080
- 29 + 82051 = 82080
- 41 + 82039 = 82080
- 43 + 82037 = 82080
- 59 + 82021 = 82080
- 67 + 82013 = 82080
- 71 + 82009 = 82080
Showing the first eight; more decompositions exist.
