Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166358, here are decompositions:
- 7 + 166351 = 166358
- 61 + 166297 = 166358
- 139 + 166219 = 166358
- 151 + 166207 = 166358
- 211 + 166147 = 166358
- 277 + 166081 = 166358
- 331 + 166027 = 166358
- 337 + 166021 = 166358
Showing the first eight; more decompositions exist.
