Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105558, here are decompositions:
- 17 + 105541 = 105558
- 29 + 105529 = 105558
- 31 + 105527 = 105558
- 41 + 105517 = 105558
- 59 + 105499 = 105558
- 67 + 105491 = 105558
- 109 + 105449 = 105558
- 151 + 105407 = 105558
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 105,558 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
