Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57666, here are decompositions:
- 13 + 57653 = 57666
- 17 + 57649 = 57666
- 29 + 57637 = 57666
- 73 + 57593 = 57666
- 79 + 57587 = 57666
- 107 + 57559 = 57666
- 109 + 57557 = 57666
- 137 + 57529 = 57666
Showing the first eight; more decompositions exist.
