Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025086, here are decompositions:

5 + 1025081 = 1025086
47 + 1025039 = 1025086
89 + 1024997 = 1025086
233 + 1024853 = 1025086
263 + 1024823 = 1025086
383 + 1024703 = 1025086
389 + 1024697 = 1025086
509 + 1024577 = 1025086

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 1,025,086 and was likely granted around 1912.

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