Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15404, here are decompositions:
- 3 + 15401 = 15404
- 13 + 15391 = 15404
- 31 + 15373 = 15404
- 43 + 15361 = 15404
- 73 + 15331 = 15404
- 97 + 15307 = 15404
- 127 + 15277 = 15404
- 163 + 15241 = 15404
Showing the first eight; more decompositions exist.
