Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002550, here are decompositions:

23 + 1002527 = 1002550
47 + 1002503 = 1002550
83 + 1002467 = 1002550
173 + 1002377 = 1002550
191 + 1002359 = 1002550
251 + 1002299 = 1002550
293 + 1002257 = 1002550
359 + 1002191 = 1002550

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 1,002,550 and was likely granted around 1911.

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