Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82178, here are decompositions:
- 7 + 82171 = 82178
- 37 + 82141 = 82178
- 127 + 82051 = 82178
- 139 + 82039 = 82178
- 157 + 82021 = 82178
- 211 + 81967 = 82178
- 241 + 81937 = 82178
- 277 + 81901 = 82178
Showing the first eight; more decompositions exist.
