Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17892, here are decompositions:
- 11 + 17881 = 17892
- 29 + 17863 = 17892
- 41 + 17851 = 17892
- 53 + 17839 = 17892
- 101 + 17791 = 17892
- 103 + 17789 = 17892
- 109 + 17783 = 17892
- 131 + 17761 = 17892
Showing the first eight; more decompositions exist.
