Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19950, here are decompositions:
- 13 + 19937 = 19950
- 23 + 19927 = 19950
- 31 + 19919 = 19950
- 37 + 19913 = 19950
- 59 + 19891 = 19950
- 61 + 19889 = 19950
- 83 + 19867 = 19950
- 89 + 19861 = 19950
Showing the first eight; more decompositions exist.
