Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15288, here are decompositions:
- 11 + 15277 = 15288
- 17 + 15271 = 15288
- 19 + 15269 = 15288
- 29 + 15259 = 15288
- 47 + 15241 = 15288
- 61 + 15227 = 15288
- 71 + 15217 = 15288
- 89 + 15199 = 15288
Showing the first eight; more decompositions exist.
