Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19080, here are decompositions:
- 7 + 19073 = 19080
- 11 + 19069 = 19080
- 29 + 19051 = 19080
- 43 + 19037 = 19080
- 67 + 19013 = 19080
- 71 + 19009 = 19080
- 79 + 19001 = 19080
- 101 + 18979 = 19080
Showing the first eight; more decompositions exist.
