Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494, here are decompositions:
- 5 + 31489 = 31494
- 13 + 31481 = 31494
- 17 + 31477 = 31494
- 97 + 31397 = 31494
- 101 + 31393 = 31494
- 103 + 31391 = 31494
- 107 + 31387 = 31494
- 137 + 31357 = 31494
Showing the first eight; more decompositions exist.
