Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19344, here are decompositions:
- 11 + 19333 = 19344
- 43 + 19301 = 19344
- 71 + 19273 = 19344
- 107 + 19237 = 19344
- 113 + 19231 = 19344
- 131 + 19213 = 19344
- 137 + 19207 = 19344
- 163 + 19181 = 19344
Showing the first eight; more decompositions exist.
