Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061840, here are decompositions:

61 + 1061779 = 1061840
67 + 1061773 = 1061840
103 + 1061737 = 1061840
151 + 1061689 = 1061840
163 + 1061677 = 1061840
193 + 1061647 = 1061840
211 + 1061629 = 1061840
223 + 1061617 = 1061840

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 6, 1840 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1840-06-01 (DMMYYYY (Euro, single-digit day))
1840-10-06 (MMDYYYY (US, single-digit day))
1840-06-10 (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 1,061,840 and was likely granted around 1912.

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