Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57724, here are decompositions:
- 5 + 57719 = 57724
- 11 + 57713 = 57724
- 71 + 57653 = 57724
- 83 + 57641 = 57724
- 131 + 57593 = 57724
- 137 + 57587 = 57724
- 167 + 57557 = 57724
- 197 + 57527 = 57724
Showing the first eight; more decompositions exist.
