Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178074, here are decompositions:

5 + 178069 = 178074
7 + 178067 = 178074
37 + 178037 = 178074
53 + 178021 = 178074
73 + 178001 = 178074
107 + 177967 = 178074
131 + 177943 = 178074
157 + 177917 = 178074

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 178,074 and was likely granted around 1874.

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