Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19456, here are decompositions:
- 23 + 19433 = 19456
- 29 + 19427 = 19456
- 53 + 19403 = 19456
- 83 + 19373 = 19456
- 137 + 19319 = 19456
- 167 + 19289 = 19456
- 197 + 19259 = 19456
- 293 + 19163 = 19456
Showing the first eight; more decompositions exist.
