Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021996, here are decompositions:

23 + 1021973 = 1021996
89 + 1021907 = 1021996
197 + 1021799 = 1021996
419 + 1021577 = 1021996
509 + 1021487 = 1021996
593 + 1021403 = 1021996
743 + 1021253 = 1021996
797 + 1021199 = 1021996

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 1996 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1996-02-01 (DMMYYYY (Euro, single-digit day))
1996-10-02 (MMDYYYY (US, single-digit day))
1996-02-10 (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 1,021,996 and was likely granted around 1912.

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