Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31424, here are decompositions:
- 31 + 31393 = 31424
- 37 + 31387 = 31424
- 67 + 31357 = 31424
- 97 + 31327 = 31424
- 103 + 31321 = 31424
- 157 + 31267 = 31424
- 193 + 31231 = 31424
- 241 + 31183 = 31424
Showing the first eight; more decompositions exist.
