Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166468, here are decompositions:
- 11 + 166457 = 166468
- 59 + 166409 = 166468
- 149 + 166319 = 166468
- 167 + 166301 = 166468
- 179 + 166289 = 166468
- 311 + 166157 = 166468
- 317 + 166151 = 166468
- 521 + 165947 = 166468
Showing the first eight; more decompositions exist.
