Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13708, here are decompositions:
- 11 + 13697 = 13708
- 17 + 13691 = 13708
- 29 + 13679 = 13708
- 59 + 13649 = 13708
- 89 + 13619 = 13708
- 131 + 13577 = 13708
- 239 + 13469 = 13708
- 251 + 13457 = 13708
Showing the first eight; more decompositions exist.
