Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042290, here are decompositions:

17 + 1042273 = 1042290
19 + 1042271 = 1042290
23 + 1042267 = 1042290
31 + 1042259 = 1042290
47 + 1042243 = 1042290
79 + 1042211 = 1042290
97 + 1042193 = 1042290
103 + 1042187 = 1042290

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 2290 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

2290-04-01 (DMMYYYY (Euro, single-digit day))
2290-10-04 (MMDYYYY (US, single-digit day))
2290-04-10 (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 1,042,290 and was likely granted around 1912.

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