Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464, here are decompositions:
- 67 + 31397 = 31464
- 71 + 31393 = 31464
- 73 + 31391 = 31464
- 107 + 31357 = 31464
- 127 + 31337 = 31464
- 131 + 31333 = 31464
- 137 + 31327 = 31464
- 157 + 31307 = 31464
Showing the first eight; more decompositions exist.
