Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042200, here are decompositions:

7 + 1042193 = 1042200
13 + 1042187 = 1042200
17 + 1042183 = 1042200
59 + 1042141 = 1042200
67 + 1042133 = 1042200
79 + 1042121 = 1042200
97 + 1042103 = 1042200
101 + 1042099 = 1042200

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 2200 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

2200-04-01 (DMMYYYY (Euro, single-digit day))
2200-10-04 (MMDYYYY (US, single-digit day))
2200-04-10 (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 1,042,200 and was likely granted around 1912.

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