Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13860, here are decompositions:
- 19 + 13841 = 13860
- 29 + 13831 = 13860
- 31 + 13829 = 13860
- 53 + 13807 = 13860
- 61 + 13799 = 13860
- 71 + 13789 = 13860
- 79 + 13781 = 13860
- 97 + 13763 = 13860
Showing the first eight; more decompositions exist.
