Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13536, here are decompositions:
- 13 + 13523 = 13536
- 23 + 13513 = 13536
- 37 + 13499 = 13536
- 59 + 13477 = 13536
- 67 + 13469 = 13536
- 73 + 13463 = 13536
- 79 + 13457 = 13536
- 137 + 13399 = 13536
Showing the first eight; more decompositions exist.
