Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105888, here are decompositions:
- 5 + 105883 = 105888
- 17 + 105871 = 105888
- 59 + 105829 = 105888
- 71 + 105817 = 105888
- 127 + 105761 = 105888
- 137 + 105751 = 105888
- 197 + 105691 = 105888
- 239 + 105649 = 105888
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105 888 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
