Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105570, here are decompositions:
- 7 + 105563 = 105570
- 13 + 105557 = 105570
- 29 + 105541 = 105570
- 37 + 105533 = 105570
- 41 + 105529 = 105570
- 43 + 105527 = 105570
- 53 + 105517 = 105570
- 61 + 105509 = 105570
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 105.570 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
