Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166486, here are decompositions:
- 29 + 166457 = 166486
- 83 + 166403 = 166486
- 137 + 166349 = 166486
- 167 + 166319 = 166486
- 197 + 166289 = 166486
- 227 + 166259 = 166486
- 239 + 166247 = 166486
- 317 + 166169 = 166486
Showing the first eight; more decompositions exist.
