Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13842, here are decompositions:
- 11 + 13831 = 13842
- 13 + 13829 = 13842
- 43 + 13799 = 13842
- 53 + 13789 = 13842
- 61 + 13781 = 13842
- 79 + 13763 = 13842
- 83 + 13759 = 13842
- 113 + 13729 = 13842
Showing the first eight; more decompositions exist.
