Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008900, here are decompositions:

29 + 1008871 = 1008900
37 + 1008863 = 1008900
41 + 1008859 = 1008900
43 + 1008857 = 1008900
47 + 1008853 = 1008900
71 + 1008829 = 1008900
83 + 1008817 = 1008900
107 + 1008793 = 1008900

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 1,008,900 and was likely granted around 1911.

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