Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105538, here are decompositions:
- 5 + 105533 = 105538
- 11 + 105527 = 105538
- 29 + 105509 = 105538
- 47 + 105491 = 105538
- 71 + 105467 = 105538
- 89 + 105449 = 105538
- 101 + 105437 = 105538
- 131 + 105407 = 105538
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 105.538 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
