Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178008, here are decompositions:

7 + 178001 = 178008
29 + 177979 = 178008
41 + 177967 = 178008
59 + 177949 = 178008
79 + 177929 = 178008
101 + 177907 = 178008
167 + 177841 = 178008
197 + 177811 = 178008

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 178,008 and was likely granted around 1874.

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