Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166240, here are decompositions:
- 3 + 166237 = 166240
- 71 + 166169 = 166240
- 83 + 166157 = 166240
- 89 + 166151 = 166240
- 197 + 166043 = 166240
- 227 + 166013 = 166240
- 257 + 165983 = 166240
- 293 + 165947 = 166240
Showing the first eight; more decompositions exist.
