Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91688, here are decompositions:
- 67 + 91621 = 91688
- 97 + 91591 = 91688
- 229 + 91459 = 91688
- 277 + 91411 = 91688
- 307 + 91381 = 91688
- 379 + 91309 = 91688
- 397 + 91291 = 91688
- 439 + 91249 = 91688
Showing the first eight; more decompositions exist.
