Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31404, here are decompositions:
- 7 + 31397 = 31404
- 11 + 31393 = 31404
- 13 + 31391 = 31404
- 17 + 31387 = 31404
- 47 + 31357 = 31404
- 67 + 31337 = 31404
- 71 + 31333 = 31404
- 83 + 31321 = 31404
Showing the first eight; more decompositions exist.
