Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57720, here are decompositions:
- 7 + 57713 = 57720
- 11 + 57709 = 57720
- 23 + 57697 = 57720
- 31 + 57689 = 57720
- 41 + 57679 = 57720
- 53 + 57667 = 57720
- 67 + 57653 = 57720
- 71 + 57649 = 57720
Showing the first eight; more decompositions exist.
