Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15766, here are decompositions:
- 5 + 15761 = 15766
- 17 + 15749 = 15766
- 29 + 15737 = 15766
- 83 + 15683 = 15766
- 137 + 15629 = 15766
- 197 + 15569 = 15766
- 239 + 15527 = 15766
- 269 + 15497 = 15766
Showing the first eight; more decompositions exist.
