Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19404, here are decompositions:
- 13 + 19391 = 19404
- 17 + 19387 = 19404
- 23 + 19381 = 19404
- 31 + 19373 = 19404
- 71 + 19333 = 19404
- 103 + 19301 = 19404
- 131 + 19273 = 19404
- 137 + 19267 = 19404
Showing the first eight; more decompositions exist.
