Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57730, here are decompositions:
- 3 + 57727 = 57730
- 11 + 57719 = 57730
- 17 + 57713 = 57730
- 41 + 57689 = 57730
- 89 + 57641 = 57730
- 137 + 57593 = 57730
- 173 + 57557 = 57730
- 227 + 57503 = 57730
Showing the first eight; more decompositions exist.
