Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021966, here are decompositions:

3 + 1021963 = 1021966
5 + 1021961 = 1021966
47 + 1021919 = 1021966
59 + 1021907 = 1021966
167 + 1021799 = 1021966
173 + 1021793 = 1021966
269 + 1021697 = 1021966
293 + 1021673 = 1021966

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 1966 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1966-02-01 (DMMYYYY (Euro, single-digit day))
1966-10-02 (MMDYYYY (US, single-digit day))
1966-02-10 (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 1,021,966 and was likely granted around 1912.

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