Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12706, here are decompositions:
- 3 + 12703 = 12706
- 17 + 12689 = 12706
- 47 + 12659 = 12706
- 53 + 12653 = 12706
- 59 + 12647 = 12706
- 137 + 12569 = 12706
- 167 + 12539 = 12706
- 179 + 12527 = 12706
Showing the first eight; more decompositions exist.
