Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108890, here are decompositions:
- 3 + 108887 = 108890
- 7 + 108883 = 108890
- 13 + 108877 = 108890
- 97 + 108793 = 108890
- 139 + 108751 = 108890
- 151 + 108739 = 108890
- 163 + 108727 = 108890
- 181 + 108709 = 108890
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 108,890 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
