Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171400, here are decompositions:

17 + 171383 = 171400
59 + 171341 = 171400
71 + 171329 = 171400
83 + 171317 = 171400
101 + 171299 = 171400
107 + 171293 = 171400
137 + 171263 = 171400
149 + 171251 = 171400

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 171,400 and was likely granted around 1874.

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