Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019040, here are decompositions:

7 + 1019033 = 1019040
17 + 1019023 = 1019040
41 + 1018999 = 1019040
47 + 1018993 = 1019040
53 + 1018987 = 1019040
59 + 1018981 = 1019040
73 + 1018967 = 1019040
83 + 1018957 = 1019040

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 9040 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

9040-10-01 (MMDYYYY (US, single-digit day))
9040-01-10 (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 1,019,040 and was likely granted around 1911.

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