Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180558, here are decompositions:

11 + 180547 = 180558
17 + 180541 = 180558
19 + 180539 = 180558
47 + 180511 = 180558
61 + 180497 = 180558
67 + 180491 = 180558
139 + 180419 = 180558
167 + 180391 = 180558

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 180,558 and was likely granted around 1875.

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