Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000940, here are decompositions:

19 + 1000921 = 1000940
79 + 1000861 = 1000940
163 + 1000777 = 1000940
271 + 1000669 = 1000940
331 + 1000609 = 1000940
433 + 1000507 = 1000940
487 + 1000453 = 1000940
547 + 1000393 = 1000940

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 1,000,940 and was likely granted around 1911.

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