Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15706, here are decompositions:
- 23 + 15683 = 15706
- 59 + 15647 = 15706
- 137 + 15569 = 15706
- 179 + 15527 = 15706
- 233 + 15473 = 15706
- 239 + 15467 = 15706
- 263 + 15443 = 15706
- 293 + 15413 = 15706
Showing the first eight; more decompositions exist.
