Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166746, here are decompositions:
- 5 + 166741 = 166746
- 7 + 166739 = 166746
- 23 + 166723 = 166746
- 43 + 166703 = 166746
- 53 + 166693 = 166746
- 67 + 166679 = 166746
- 79 + 166667 = 166746
- 89 + 166657 = 166746
Showing the first eight; more decompositions exist.
