Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105210, here are decompositions:
- 11 + 105199 = 105210
- 37 + 105173 = 105210
- 43 + 105167 = 105210
- 67 + 105143 = 105210
- 73 + 105137 = 105210
- 103 + 105107 = 105210
- 113 + 105097 = 105210
- 139 + 105071 = 105210
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 105,210 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
