Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19008, here are decompositions:
- 7 + 19001 = 19008
- 29 + 18979 = 19008
- 61 + 18947 = 19008
- 89 + 18919 = 19008
- 97 + 18911 = 19008
- 109 + 18899 = 19008
- 139 + 18869 = 19008
- 149 + 18859 = 19008
Showing the first eight; more decompositions exist.
