Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179644, here are decompositions:

11 + 179633 = 179644
41 + 179603 = 179644
53 + 179591 = 179644
71 + 179573 = 179644
173 + 179471 = 179644
191 + 179453 = 179644
233 + 179411 = 179644
251 + 179393 = 179644

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 179,644 and was likely granted around 1875.

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