Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048870, here are decompositions:

3 + 1048867 = 1048870
23 + 1048847 = 1048870
41 + 1048829 = 1048870
71 + 1048799 = 1048870
149 + 1048721 = 1048870
167 + 1048703 = 1048870
257 + 1048613 = 1048870
269 + 1048601 = 1048870

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 8870 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

8870-04-01 (DMMYYYY (Euro, single-digit day))
8870-10-04 (MMDYYYY (US, single-digit day))
8870-04-10 (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 1,048,870 and was likely granted around 1912.

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