Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028556, here are decompositions:

47 + 1028509 = 1028556
83 + 1028473 = 1028556
163 + 1028393 = 1028556
167 + 1028389 = 1028556
223 + 1028333 = 1028556
227 + 1028329 = 1028556
229 + 1028327 = 1028556
239 + 1028317 = 1028556

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 1,028,556 and was likely granted around 1912.

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