Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57540, here are decompositions:
- 11 + 57529 = 57540
- 13 + 57527 = 57540
- 37 + 57503 = 57540
- 47 + 57493 = 57540
- 53 + 57487 = 57540
- 73 + 57467 = 57540
- 83 + 57457 = 57540
- 113 + 57427 = 57540
Showing the first eight; more decompositions exist.
