Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57040, here are decompositions:
- 3 + 57037 = 57040
- 41 + 56999 = 57040
- 47 + 56993 = 57040
- 83 + 56957 = 57040
- 89 + 56951 = 57040
- 131 + 56909 = 57040
- 149 + 56891 = 57040
- 167 + 56873 = 57040
Showing the first eight; more decompositions exist.
