Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180006, here are decompositions:

5 + 180001 = 180006
7 + 179999 = 180006
17 + 179989 = 180006
37 + 179969 = 180006
53 + 179953 = 180006
59 + 179947 = 180006
67 + 179939 = 180006
83 + 179923 = 180006

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 180,006 and was likely granted around 1875.

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