Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82160, here are decompositions:
- 7 + 82153 = 82160
- 19 + 82141 = 82160
- 31 + 82129 = 82160
- 109 + 82051 = 82160
- 139 + 82021 = 82160
- 151 + 82009 = 82160
- 157 + 82003 = 82160
- 193 + 81967 = 82160
Showing the first eight; more decompositions exist.
