Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178030, here are decompositions:

29 + 178001 = 178030
101 + 177929 = 178030
113 + 177917 = 178030
137 + 177893 = 178030
191 + 177839 = 178030
233 + 177797 = 178030
239 + 177791 = 178030
269 + 177761 = 178030

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 178,030 and was likely granted around 1874.

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