Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91440, here are decompositions:
- 7 + 91433 = 91440
- 17 + 91423 = 91440
- 29 + 91411 = 91440
- 43 + 91397 = 91440
- 47 + 91393 = 91440
- 53 + 91387 = 91440
- 59 + 91381 = 91440
- 67 + 91373 = 91440
Showing the first eight; more decompositions exist.
