Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105572, here are decompositions:
- 31 + 105541 = 105572
- 43 + 105529 = 105572
- 73 + 105499 = 105572
- 193 + 105379 = 105572
- 199 + 105373 = 105572
- 211 + 105361 = 105572
- 241 + 105331 = 105572
- 373 + 105199 = 105572
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 105.572 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
