Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15276, here are decompositions:
- 5 + 15271 = 15276
- 7 + 15269 = 15276
- 13 + 15263 = 15276
- 17 + 15259 = 15276
- 43 + 15233 = 15276
- 59 + 15217 = 15276
- 83 + 15193 = 15276
- 89 + 15187 = 15276
Showing the first eight; more decompositions exist.
