Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180756, here are decompositions:

5 + 180751 = 180756
7 + 180749 = 180756
89 + 180667 = 180756
109 + 180647 = 180756
127 + 180629 = 180756
139 + 180617 = 180756
193 + 180563 = 180756
223 + 180533 = 180756

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 180,756 and was likely granted around 1875.

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