Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180470, here are decompositions:

7 + 180463 = 180470
79 + 180391 = 180470
109 + 180361 = 180470
139 + 180331 = 180470
163 + 180307 = 180470
181 + 180289 = 180470
211 + 180259 = 180470
223 + 180247 = 180470

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 180,470 and was likely granted around 1875.

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