Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105200, here are decompositions:
- 103 + 105097 = 105200
- 163 + 105037 = 105200
- 181 + 105019 = 105200
- 229 + 104971 = 105200
- 241 + 104959 = 105200
- 283 + 104917 = 105200
- 331 + 104869 = 105200
- 349 + 104851 = 105200
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 105 200 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
