Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498, here are decompositions:
- 17 + 31481 = 31498
- 29 + 31469 = 31498
- 101 + 31397 = 31498
- 107 + 31391 = 31498
- 179 + 31319 = 31498
- 191 + 31307 = 31498
- 227 + 31271 = 31498
- 239 + 31259 = 31498
Showing the first eight; more decompositions exist.
