Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105162, here are decompositions:
- 19 + 105143 = 105162
- 131 + 105031 = 105162
- 139 + 105023 = 105162
- 163 + 104999 = 105162
- 191 + 104971 = 105162
- 229 + 104933 = 105162
- 251 + 104911 = 105162
- 271 + 104891 = 105162
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 105,162 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
