Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001450, here are decompositions:

3 + 1001447 = 1001450
19 + 1001431 = 1001450
61 + 1001389 = 1001450
97 + 1001353 = 1001450
103 + 1001347 = 1001450
127 + 1001323 = 1001450
139 + 1001311 = 1001450
277 + 1001173 = 1001450

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 1,001,450 and was likely granted around 1911.

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