Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179648, here are decompositions:

67 + 179581 = 179648
151 + 179497 = 179648
211 + 179437 = 179648
241 + 179407 = 179648
331 + 179317 = 179648
367 + 179281 = 179648
379 + 179269 = 179648
439 + 179209 = 179648

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 179,648 and was likely granted around 1875.

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