Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105890, here are decompositions:
- 7 + 105883 = 105890
- 19 + 105871 = 105890
- 61 + 105829 = 105890
- 73 + 105817 = 105890
- 139 + 105751 = 105890
- 157 + 105733 = 105890
- 163 + 105727 = 105890
- 199 + 105691 = 105890
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 105.890 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
