Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12432, here are decompositions:
- 11 + 12421 = 12432
- 19 + 12413 = 12432
- 23 + 12409 = 12432
- 31 + 12401 = 12432
- 41 + 12391 = 12432
- 53 + 12379 = 12432
- 59 + 12373 = 12432
- 89 + 12343 = 12432
Showing the first eight; more decompositions exist.
