Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13832, here are decompositions:
- 3 + 13829 = 13832
- 43 + 13789 = 13832
- 73 + 13759 = 13832
- 103 + 13729 = 13832
- 109 + 13723 = 13832
- 139 + 13693 = 13832
- 151 + 13681 = 13832
- 163 + 13669 = 13832
Showing the first eight; more decompositions exist.
