Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051802, here are decompositions:

13 + 1051789 = 1051802
43 + 1051759 = 1051802
139 + 1051663 = 1051802
163 + 1051639 = 1051802
181 + 1051621 = 1051802
211 + 1051591 = 1051802
331 + 1051471 = 1051802
379 + 1051423 = 1051802

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 5, 1802 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1802-05-01 (DMMYYYY (Euro, single-digit day))
1802-10-05 (MMDYYYY (US, single-digit day))
1802-05-10 (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 1,051,802 and was likely granted around 1912.

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