Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180354, here are decompositions:

7 + 180347 = 180354
17 + 180337 = 180354
23 + 180331 = 180354
37 + 180317 = 180354
43 + 180311 = 180354
47 + 180307 = 180354
67 + 180287 = 180354
73 + 180281 = 180354

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 180,354 and was likely granted around 1875.

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