Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000158, here are decompositions:

7 + 1000151 = 1000158
37 + 1000121 = 1000158
41 + 1000117 = 1000158
59 + 1000099 = 1000158
179 + 999979 = 1000158
197 + 999961 = 1000158
199 + 999959 = 1000158
227 + 999931 = 1000158

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 1,000,158 and was likely granted around 1911.

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