Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180306, here are decompositions:

17 + 180289 = 180306
19 + 180287 = 180306
43 + 180263 = 180306
47 + 180259 = 180306
59 + 180247 = 180306
67 + 180239 = 180306
73 + 180233 = 180306
127 + 180179 = 180306

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 180,306 and was likely granted around 1875.

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