Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180202, here are decompositions:

23 + 180179 = 180202
41 + 180161 = 180202
131 + 180071 = 180202
149 + 180053 = 180202
179 + 180023 = 180202
233 + 179969 = 180202
251 + 179951 = 180202
263 + 179939 = 180202

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 180,202 and was likely granted around 1875.

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