Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166550, here are decompositions:
- 79 + 166471 = 166550
- 151 + 166399 = 166550
- 157 + 166393 = 166550
- 193 + 166357 = 166550
- 199 + 166351 = 166550
- 277 + 166273 = 166550
- 313 + 166237 = 166550
- 331 + 166219 = 166550
Showing the first eight; more decompositions exist.
