Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016840, here are decompositions:

67 + 1016773 = 1016840
103 + 1016737 = 1016840
109 + 1016731 = 1016840
151 + 1016689 = 1016840
199 + 1016641 = 1016840
229 + 1016611 = 1016840
241 + 1016599 = 1016840
271 + 1016569 = 1016840

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 6840 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

6840-10-01 (MMDYYYY (US, single-digit day))
6840-01-10 (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 1,016,840 and was likely granted around 1911.

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