Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185460, here are decompositions:

19 + 185441 = 185460
31 + 185429 = 185460
59 + 185401 = 185460
89 + 185371 = 185460
97 + 185363 = 185460
101 + 185359 = 185460
137 + 185323 = 185460
151 + 185309 = 185460

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 185,460 and was likely granted around 1875.

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