Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82180, here are decompositions:
- 17 + 82163 = 82180
- 41 + 82139 = 82180
- 107 + 82073 = 82180
- 113 + 82067 = 82180
- 149 + 82031 = 82180
- 167 + 82013 = 82180
- 173 + 82007 = 82180
- 227 + 81953 = 82180
Showing the first eight; more decompositions exist.
