Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028500, here are decompositions:

29 + 1028471 = 1028500
89 + 1028411 = 1028500
107 + 1028393 = 1028500
167 + 1028333 = 1028500
173 + 1028327 = 1028500
191 + 1028309 = 1028500
197 + 1028303 = 1028500
227 + 1028273 = 1028500

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 1,028,500 and was likely granted around 1912.

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