Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598, here are decompositions:
- 31 + 31567 = 31598
- 67 + 31531 = 31598
- 109 + 31489 = 31598
- 211 + 31387 = 31598
- 241 + 31357 = 31598
- 271 + 31327 = 31598
- 277 + 31321 = 31598
- 331 + 31267 = 31598
Showing the first eight; more decompositions exist.
