Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002806, here are decompositions:

19 + 1002787 = 1002806
37 + 1002769 = 1002806
67 + 1002739 = 1002806
97 + 1002709 = 1002806
127 + 1002679 = 1002806
223 + 1002583 = 1002806
229 + 1002577 = 1002806
283 + 1002523 = 1002806

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 1,002,806 and was likely granted around 1911.

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