Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105444, here are decompositions:
- 7 + 105437 = 105444
- 37 + 105407 = 105444
- 43 + 105401 = 105444
- 47 + 105397 = 105444
- 71 + 105373 = 105444
- 83 + 105361 = 105444
- 103 + 105341 = 105444
- 107 + 105337 = 105444
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 105 444 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
