Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31416, here are decompositions:
- 19 + 31397 = 31416
- 23 + 31393 = 31416
- 29 + 31387 = 31416
- 37 + 31379 = 31416
- 59 + 31357 = 31416
- 79 + 31337 = 31416
- 83 + 31333 = 31416
- 89 + 31327 = 31416
Showing the first eight; more decompositions exist.
