Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105668, here are decompositions:
- 19 + 105649 = 105668
- 61 + 105607 = 105668
- 67 + 105601 = 105668
- 127 + 105541 = 105668
- 139 + 105529 = 105668
- 151 + 105517 = 105668
- 271 + 105397 = 105668
- 307 + 105361 = 105668
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 105.668 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
