Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180584, here are decompositions:

37 + 180547 = 180584
43 + 180541 = 180584
73 + 180511 = 180584
193 + 180391 = 180584
223 + 180361 = 180584
277 + 180307 = 180584
337 + 180247 = 180584
373 + 180211 = 180584

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 180,584 and was likely granted around 1875.

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