Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19338, here are decompositions:
- 5 + 19333 = 19338
- 19 + 19319 = 19338
- 29 + 19309 = 19338
- 37 + 19301 = 19338
- 71 + 19267 = 19338
- 79 + 19259 = 19338
- 89 + 19249 = 19338
- 101 + 19237 = 19338
Showing the first eight; more decompositions exist.
