Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171230, here are decompositions:

61 + 171169 = 171230
67 + 171163 = 171230
127 + 171103 = 171230
139 + 171091 = 171230
151 + 171079 = 171230
181 + 171049 = 171230
223 + 171007 = 171230
277 + 170953 = 171230

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 171,230 and was likely granted around 1874.

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