Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047800, here are decompositions:

37 + 1047763 = 1047800
79 + 1047721 = 1047800
97 + 1047703 = 1047800
109 + 1047691 = 1047800
151 + 1047649 = 1047800
211 + 1047589 = 1047800
241 + 1047559 = 1047800
331 + 1047469 = 1047800

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 7800 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

7800-04-01 (DMMYYYY (Euro, single-digit day))
7800-10-04 (MMDYYYY (US, single-digit day))
7800-04-10 (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 1,047,800 and was likely granted around 1912.

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