Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178000, here are decompositions:

47 + 177953 = 178000
71 + 177929 = 178000
83 + 177917 = 178000
107 + 177893 = 178000
113 + 177887 = 178000
239 + 177761 = 178000
257 + 177743 = 178000
353 + 177647 = 178000

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 178,000 and was likely granted around 1874.

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