Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460, here are decompositions:
- 67 + 31393 = 31460
- 73 + 31387 = 31460
- 103 + 31357 = 31460
- 127 + 31333 = 31460
- 139 + 31321 = 31460
- 193 + 31267 = 31460
- 211 + 31249 = 31460
- 223 + 31237 = 31460
Showing the first eight; more decompositions exist.
