Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13886, here are decompositions:
- 3 + 13883 = 13886
- 7 + 13879 = 13886
- 13 + 13873 = 13886
- 79 + 13807 = 13886
- 97 + 13789 = 13886
- 127 + 13759 = 13886
- 157 + 13729 = 13886
- 163 + 13723 = 13886
Showing the first eight; more decompositions exist.
