Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13726, here are decompositions:
- 3 + 13723 = 13726
- 5 + 13721 = 13726
- 17 + 13709 = 13726
- 29 + 13697 = 13726
- 47 + 13679 = 13726
- 107 + 13619 = 13726
- 113 + 13613 = 13726
- 149 + 13577 = 13726
Showing the first eight; more decompositions exist.
