Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31682, here are decompositions:
- 19 + 31663 = 31682
- 109 + 31573 = 31682
- 139 + 31543 = 31682
- 151 + 31531 = 31682
- 193 + 31489 = 31682
- 349 + 31333 = 31682
- 433 + 31249 = 31682
- 463 + 31219 = 31682
Showing the first eight; more decompositions exist.
