Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16448, here are decompositions:
- 31 + 16417 = 16448
- 37 + 16411 = 16448
- 67 + 16381 = 16448
- 79 + 16369 = 16448
- 109 + 16339 = 16448
- 181 + 16267 = 16448
- 199 + 16249 = 16448
- 307 + 16141 = 16448
Showing the first eight; more decompositions exist.
