Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105178, here are decompositions:
- 5 + 105173 = 105178
- 11 + 105167 = 105178
- 41 + 105137 = 105178
- 71 + 105107 = 105178
- 107 + 105071 = 105178
- 179 + 104999 = 105178
- 191 + 104987 = 105178
- 347 + 104831 = 105178
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 105.178 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
