Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180754, here are decompositions:

3 + 180751 = 180754
5 + 180749 = 180754
23 + 180731 = 180754
53 + 180701 = 180754
107 + 180647 = 180754
131 + 180623 = 180754
137 + 180617 = 180754
191 + 180563 = 180754

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 180,754 and was likely granted around 1875.

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