Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19896, here are decompositions:
- 5 + 19891 = 19896
- 7 + 19889 = 19896
- 29 + 19867 = 19896
- 43 + 19853 = 19896
- 53 + 19843 = 19896
- 83 + 19813 = 19896
- 103 + 19793 = 19896
- 137 + 19759 = 19896
Showing the first eight; more decompositions exist.
