Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617922, here are decompositions:
- 23 + 31617899 = 31617922
- 59 + 31617863 = 31617922
- 233 + 31617689 = 31617922
- 263 + 31617659 = 31617922
- 293 + 31617629 = 31617922
- 359 + 31617563 = 31617922
- 389 + 31617533 = 31617922
- 419 + 31617503 = 31617922
Showing the first eight; more decompositions exist.
