Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042456, here are decompositions:

5 + 1042451 = 1042456
17 + 1042439 = 1042456
29 + 1042427 = 1042456
83 + 1042373 = 1042456
197 + 1042259 = 1042456
263 + 1042193 = 1042456
269 + 1042187 = 1042456
347 + 1042109 = 1042456

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 2456 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

2456-04-01 (DMMYYYY (Euro, single-digit day))
2456-10-04 (MMDYYYY (US, single-digit day))
2456-04-10 (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 1,042,456 and was likely granted around 1912.

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