Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13584, here are decompositions:
- 7 + 13577 = 13584
- 17 + 13567 = 13584
- 31 + 13553 = 13584
- 47 + 13537 = 13584
- 61 + 13523 = 13584
- 71 + 13513 = 13584
- 97 + 13487 = 13584
- 107 + 13477 = 13584
Showing the first eight; more decompositions exist.
