Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501158, here are decompositions:

19 + 501139 = 501158
37 + 501121 = 501158
127 + 501031 = 501158
139 + 501019 = 501158
157 + 501001 = 501158
181 + 500977 = 501158
211 + 500947 = 501158
271 + 500887 = 501158

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 501,158 and was likely granted around 1893.

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