Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048400, here are decompositions:

13 + 1048387 = 1048400
43 + 1048357 = 1048400
109 + 1048291 = 1048400
127 + 1048273 = 1048400
139 + 1048261 = 1048400
181 + 1048219 = 1048400
211 + 1048189 = 1048400
271 + 1048129 = 1048400

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 8400 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

8400-04-01 (DMMYYYY (Euro, single-digit day))
8400-10-04 (MMDYYYY (US, single-digit day))
8400-04-10 (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 1,048,400 and was likely granted around 1912.

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