Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188830, here are decompositions:

3 + 188827 = 188830
29 + 188801 = 188830
101 + 188729 = 188830
137 + 188693 = 188830
149 + 188681 = 188830
197 + 188633 = 188830
227 + 188603 = 188830
251 + 188579 = 188830

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 188,830 and was likely granted around 1875.

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