Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019000, here are decompositions:

7 + 1018993 = 1019000
13 + 1018987 = 1019000
19 + 1018981 = 1019000
43 + 1018957 = 1019000
97 + 1018903 = 1019000
127 + 1018873 = 1019000
193 + 1018807 = 1019000
211 + 1018789 = 1019000

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 9000 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

9000-10-01 (MMDYYYY (US, single-digit day))
9000-01-10 (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 1,019,000 and was likely granted around 1911.

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