Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180888, here are decompositions:

5 + 180883 = 180888
17 + 180871 = 180888
41 + 180847 = 180888
89 + 180799 = 180888
109 + 180779 = 180888
137 + 180751 = 180888
139 + 180749 = 180888
157 + 180731 = 180888

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 180,888 and was likely granted around 1875.

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