Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185144, here are decompositions:

7 + 185137 = 185144
13 + 185131 = 185144
67 + 185077 = 185144
73 + 185071 = 185144
151 + 184993 = 185144
241 + 184903 = 185144
307 + 184837 = 185144
313 + 184831 = 185144

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 185,144 and was likely granted around 1875.

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