Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011900, here are decompositions:

7 + 1011893 = 1011900
11 + 1011889 = 1011900
73 + 1011827 = 1011900
83 + 1011817 = 1011900
101 + 1011799 = 1011900
103 + 1011797 = 1011900
137 + 1011763 = 1011900
151 + 1011749 = 1011900

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 1900 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

1900-10-01 (MMDYYYY (US, single-digit day))
1900-01-10 (DDMYYYY (Euro, single-digit month))

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 1,011,900 and was likely granted around 1911.

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