Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031258, here are decompositions:

97 + 1031161 = 1031258
139 + 1031119 = 1031258
211 + 1031047 = 1031258
271 + 1030987 = 1031258
307 + 1030951 = 1031258
457 + 1030801 = 1031258
499 + 1030759 = 1031258
577 + 1030681 = 1031258

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 1,031,258 and was likely granted around 1912.

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