Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17938, here are decompositions:
- 17 + 17921 = 17938
- 29 + 17909 = 17938
- 47 + 17891 = 17938
- 101 + 17837 = 17938
- 131 + 17807 = 17938
- 149 + 17789 = 17938
- 191 + 17747 = 17938
- 257 + 17681 = 17938
Showing the first eight; more decompositions exist.
