Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188864, here are decompositions:

3 + 188861 = 188864
7 + 188857 = 188864
31 + 188833 = 188864
37 + 188827 = 188864
73 + 188791 = 188864
97 + 188767 = 188864
157 + 188707 = 188864
163 + 188701 = 188864

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 188,864 and was likely granted around 1875.

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