Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105530, here are decompositions:
- 3 + 105527 = 105530
- 13 + 105517 = 105530
- 31 + 105499 = 105530
- 151 + 105379 = 105530
- 157 + 105373 = 105530
- 163 + 105367 = 105530
- 193 + 105337 = 105530
- 199 + 105331 = 105530
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 105,530 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
