Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019258, here are decompositions:

7 + 1019251 = 1019258
61 + 1019197 = 1019258
139 + 1019119 = 1019258
181 + 1019077 = 1019258
199 + 1019059 = 1019258
271 + 1018987 = 1019258
277 + 1018981 = 1019258
379 + 1018879 = 1019258

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 1,019,258 and was likely granted around 1911.

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