Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045456, here are decompositions:

29 + 1045427 = 1045456
47 + 1045409 = 1045456
59 + 1045397 = 1045456
89 + 1045367 = 1045456
107 + 1045349 = 1045456
149 + 1045307 = 1045456
179 + 1045277 = 1045456
227 + 1045229 = 1045456

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 4, 5456 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

5456-04-01 (DMMYYYY (Euro, single-digit day))
5456-10-04 (MMDYYYY (US, single-digit day))
5456-04-10 (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 1,045,456 and was likely granted around 1912.

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