Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050900, here are decompositions:

13 + 1050887 = 1050900
47 + 1050853 = 1050900
83 + 1050817 = 1050900
89 + 1050811 = 1050900
127 + 1050773 = 1050900
131 + 1050769 = 1050900
157 + 1050743 = 1050900
163 + 1050737 = 1050900

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 5, 0900 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0900-05-01 (DMMYYYY (Euro, single-digit day))
0900-10-05 (MMDYYYY (US, single-digit day))
0900-05-10 (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 1,050,900 and was likely granted around 1912.

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