Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15306, here are decompositions:
- 7 + 15299 = 15306
- 17 + 15289 = 15306
- 19 + 15287 = 15306
- 29 + 15277 = 15306
- 37 + 15269 = 15306
- 43 + 15263 = 15306
- 47 + 15259 = 15306
- 73 + 15233 = 15306
Showing the first eight; more decompositions exist.
