Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021910, here are decompositions:

3 + 1021907 = 1021910
13 + 1021897 = 1021910
31 + 1021879 = 1021910
61 + 1021849 = 1021910
73 + 1021837 = 1021910
79 + 1021831 = 1021910
103 + 1021807 = 1021910
151 + 1021759 = 1021910

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 1910 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1910-02-01 (DMMYYYY (Euro, single-digit day))
1910-10-02 (MMDYYYY (US, single-digit day))
1910-02-10 (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 1,021,910 and was likely granted around 1912.

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