Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17874, here are decompositions:
- 11 + 17863 = 17874
- 23 + 17851 = 17874
- 37 + 17837 = 17874
- 47 + 17827 = 17874
- 67 + 17807 = 17874
- 83 + 17791 = 17874
- 113 + 17761 = 17874
- 127 + 17747 = 17874
Showing the first eight; more decompositions exist.
