Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105772, here are decompositions:

3 + 105769 = 105772
5 + 105767 = 105772
11 + 105761 = 105772
71 + 105701 = 105772
89 + 105683 = 105772
239 + 105533 = 105772
263 + 105509 = 105772
269 + 105503 = 105772

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105 772 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
