Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106806, here are decompositions:
- 5 + 106801 = 106806
- 19 + 106787 = 106806
- 23 + 106783 = 106806
- 47 + 106759 = 106806
- 53 + 106753 = 106806
- 59 + 106747 = 106806
- 67 + 106739 = 106806
- 79 + 106727 = 106806
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 106,806 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
