Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166894, here are decompositions:
- 23 + 166871 = 166894
- 41 + 166853 = 166894
- 47 + 166847 = 166894
- 53 + 166841 = 166894
- 71 + 166823 = 166894
- 113 + 166781 = 166894
- 191 + 166703 = 166894
- 227 + 166667 = 166894
Showing the first eight; more decompositions exist.
