Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051666, here are decompositions:

3 + 1051663 = 1051666
17 + 1051649 = 1051666
23 + 1051643 = 1051666
47 + 1051619 = 1051666
59 + 1051607 = 1051666
107 + 1051559 = 1051666
113 + 1051553 = 1051666
167 + 1051499 = 1051666

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 5, 1666 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1666-05-01 (DMMYYYY (Euro, single-digit day))
1666-10-05 (MMDYYYY (US, single-digit day))
1666-05-10 (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 1,051,666 and was likely granted around 1912.

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