Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19908, here are decompositions:
- 17 + 19891 = 19908
- 19 + 19889 = 19908
- 41 + 19867 = 19908
- 47 + 19861 = 19908
- 67 + 19841 = 19908
- 89 + 19819 = 19908
- 107 + 19801 = 19908
- 131 + 19777 = 19908
Showing the first eight; more decompositions exist.
