Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496, here are decompositions:
- 7 + 31489 = 31496
- 19 + 31477 = 31496
- 103 + 31393 = 31496
- 109 + 31387 = 31496
- 139 + 31357 = 31496
- 163 + 31333 = 31496
- 229 + 31267 = 31496
- 277 + 31219 = 31496
Showing the first eight; more decompositions exist.
