Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15286, here are decompositions:
- 17 + 15269 = 15286
- 23 + 15263 = 15286
- 53 + 15233 = 15286
- 59 + 15227 = 15286
- 113 + 15173 = 15286
- 137 + 15149 = 15286
- 149 + 15137 = 15286
- 179 + 15107 = 15286
Showing the first eight; more decompositions exist.
