Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140572, here are decompositions:
- 23 + 140549 = 140572
- 149 + 140423 = 140572
- 191 + 140381 = 140572
- 233 + 140339 = 140572
- 239 + 140333 = 140572
- 251 + 140321 = 140572
- 401 + 140171 = 140572
- 449 + 140123 = 140572
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 140,572 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
