Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106866, here are decompositions:
- 5 + 106861 = 106866
- 7 + 106859 = 106866
- 13 + 106853 = 106866
- 43 + 106823 = 106866
- 79 + 106787 = 106866
- 83 + 106783 = 106866
- 107 + 106759 = 106866
- 113 + 106753 = 106866
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 106,866 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
