Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19962, here are decompositions:
- 13 + 19949 = 19962
- 43 + 19919 = 19962
- 71 + 19891 = 19962
- 73 + 19889 = 19962
- 101 + 19861 = 19962
- 109 + 19853 = 19962
- 149 + 19813 = 19962
- 199 + 19763 = 19962
Showing the first eight; more decompositions exist.
