Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180148, here are decompositions:

11 + 180137 = 180148
71 + 180077 = 180148
149 + 179999 = 180148
167 + 179981 = 180148
179 + 179969 = 180148
191 + 179957 = 180148
197 + 179951 = 180148
239 + 179909 = 180148

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 180,148 and was likely granted around 1875.

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