Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108178, here are decompositions:
- 17 + 108161 = 108178
- 47 + 108131 = 108178
- 71 + 108107 = 108178
- 89 + 108089 = 108178
- 137 + 108041 = 108178
- 167 + 108011 = 108178
- 179 + 107999 = 108178
- 197 + 107981 = 108178
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 108,178 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
