Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582, here are decompositions:
- 41 + 31541 = 31582
- 71 + 31511 = 31582
- 101 + 31481 = 31582
- 113 + 31469 = 31582
- 191 + 31391 = 31582
- 263 + 31319 = 31582
- 311 + 31271 = 31582
- 359 + 31223 = 31582
Showing the first eight; more decompositions exist.
