Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105108, here are decompositions:
- 11 + 105097 = 105108
- 37 + 105071 = 105108
- 71 + 105037 = 105108
- 89 + 105019 = 105108
- 109 + 104999 = 105108
- 137 + 104971 = 105108
- 149 + 104959 = 105108
- 191 + 104917 = 105108
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 105,108 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
