Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606, here are decompositions:
- 5 + 31601 = 31606
- 23 + 31583 = 31606
- 59 + 31547 = 31606
- 89 + 31517 = 31606
- 137 + 31469 = 31606
- 227 + 31379 = 31606
- 269 + 31337 = 31606
- 347 + 31259 = 31606
Showing the first eight; more decompositions exist.
