Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492, here are decompositions:
- 3 + 31489 = 31492
- 11 + 31481 = 31492
- 23 + 31469 = 31492
- 101 + 31391 = 31492
- 113 + 31379 = 31492
- 173 + 31319 = 31492
- 233 + 31259 = 31492
- 239 + 31253 = 31492
Showing the first eight; more decompositions exist.
