Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57742, here are decompositions:
- 5 + 57737 = 57742
- 11 + 57731 = 57742
- 23 + 57719 = 57742
- 29 + 57713 = 57742
- 53 + 57689 = 57742
- 89 + 57653 = 57742
- 101 + 57641 = 57742
- 149 + 57593 = 57742
Showing the first eight; more decompositions exist.
