Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180210, here are decompositions:

29 + 180181 = 180210
31 + 180179 = 180210
73 + 180137 = 180210
113 + 180097 = 180210
137 + 180073 = 180210
139 + 180071 = 180210
157 + 180053 = 180210
167 + 180043 = 180210

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 180,210 and was likely granted around 1875.

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