Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 448, here are decompositions:
- 5 + 443 = 448
- 17 + 431 = 448
- 29 + 419 = 448
- 47 + 401 = 448
- 59 + 389 = 448
- 89 + 359 = 448
- 101 + 347 = 448
- 131 + 317 = 448
Showing the first eight; more decompositions exist.
