Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019400, here are decompositions:

23 + 1019377 = 1019400
43 + 1019357 = 1019400
47 + 1019353 = 1019400
61 + 1019339 = 1019400
71 + 1019329 = 1019400
103 + 1019297 = 1019400
127 + 1019273 = 1019400
139 + 1019261 = 1019400

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 9400 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

9400-10-01 (MMDYYYY (US, single-digit day))
9400-01-10 (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 1,019,400 and was likely granted around 1911.

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