Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15340, here are decompositions:
- 11 + 15329 = 15340
- 41 + 15299 = 15340
- 53 + 15287 = 15340
- 71 + 15269 = 15340
- 107 + 15233 = 15340
- 113 + 15227 = 15340
- 167 + 15173 = 15340
- 179 + 15161 = 15340
Showing the first eight; more decompositions exist.
