Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043806, here are decompositions:

47 + 1043759 = 1043806
53 + 1043753 = 1043806
59 + 1043747 = 1043806
83 + 1043723 = 1043806
149 + 1043657 = 1043806
167 + 1043639 = 1043806
263 + 1043543 = 1043806
293 + 1043513 = 1043806

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 3806 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

3806-04-01 (DMMYYYY (Euro, single-digit day))
3806-10-04 (MMDYYYY (US, single-digit day))
3806-04-10 (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 1,043,806 and was likely granted around 1912.

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