Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105368, here are decompositions:
- 7 + 105361 = 105368
- 31 + 105337 = 105368
- 37 + 105331 = 105368
- 139 + 105229 = 105368
- 157 + 105211 = 105368
- 271 + 105097 = 105368
- 331 + 105037 = 105368
- 337 + 105031 = 105368
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 105,368 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
