Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18996, here are decompositions:
- 17 + 18979 = 18996
- 23 + 18973 = 18996
- 37 + 18959 = 18996
- 79 + 18917 = 18996
- 83 + 18913 = 18996
- 97 + 18899 = 18996
- 127 + 18869 = 18996
- 137 + 18859 = 18996
Showing the first eight; more decompositions exist.
