Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106890, here are decompositions:
- 13 + 106877 = 106890
- 19 + 106871 = 106890
- 23 + 106867 = 106890
- 29 + 106861 = 106890
- 31 + 106859 = 106890
- 37 + 106853 = 106890
- 67 + 106823 = 106890
- 89 + 106801 = 106890
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 106,890 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
