Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17888, here are decompositions:
- 7 + 17881 = 17888
- 37 + 17851 = 17888
- 61 + 17827 = 17888
- 97 + 17791 = 17888
- 127 + 17761 = 17888
- 139 + 17749 = 17888
- 151 + 17737 = 17888
- 181 + 17707 = 17888
Showing the first eight; more decompositions exist.
