Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484, here are decompositions:
- 3 + 31481 = 31484
- 7 + 31477 = 31484
- 97 + 31387 = 31484
- 127 + 31357 = 31484
- 151 + 31333 = 31484
- 157 + 31327 = 31484
- 163 + 31321 = 31484
- 307 + 31177 = 31484
Showing the first eight; more decompositions exist.
