Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20448, here are decompositions:
- 5 + 20443 = 20448
- 7 + 20441 = 20448
- 17 + 20431 = 20448
- 37 + 20411 = 20448
- 41 + 20407 = 20448
- 59 + 20389 = 20448
- 79 + 20369 = 20448
- 89 + 20359 = 20448
Showing the first eight; more decompositions exist.
