Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91564, here are decompositions:
- 23 + 91541 = 91564
- 71 + 91493 = 91564
- 101 + 91463 = 91564
- 107 + 91457 = 91564
- 131 + 91433 = 91564
- 167 + 91397 = 91564
- 191 + 91373 = 91564
- 197 + 91367 = 91564
Showing the first eight; more decompositions exist.
