Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4448, here are decompositions:
- 7 + 4441 = 4448
- 109 + 4339 = 4448
- 151 + 4297 = 4448
- 229 + 4219 = 4448
- 271 + 4177 = 4448
- 337 + 4111 = 4448
- 349 + 4099 = 4448
- 397 + 4051 = 4448
Showing the first eight; more decompositions exist.
