Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476, here are decompositions:
- 7 + 31469 = 31476
- 79 + 31397 = 31476
- 83 + 31393 = 31476
- 89 + 31387 = 31476
- 97 + 31379 = 31476
- 139 + 31337 = 31476
- 149 + 31327 = 31476
- 157 + 31319 = 31476
Showing the first eight; more decompositions exist.
