Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021850, here are decompositions:

13 + 1021837 = 1021850
19 + 1021831 = 1021850
43 + 1021807 = 1021850
73 + 1021777 = 1021850
97 + 1021753 = 1021850
103 + 1021747 = 1021850
139 + 1021711 = 1021850
199 + 1021651 = 1021850

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 1850 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1850-02-01 (DMMYYYY (Euro, single-digit day))
1850-10-02 (MMDYYYY (US, single-digit day))
1850-02-10 (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 1,021,850 and was likely granted around 1912.

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