Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051456, here are decompositions:

47 + 1051409 = 1051456
59 + 1051397 = 1051456
83 + 1051373 = 1051456
137 + 1051319 = 1051456
173 + 1051283 = 1051456
179 + 1051277 = 1051456
317 + 1051139 = 1051456
449 + 1051007 = 1051456

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 5, 1456 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1456-05-01 (DMMYYYY (Euro, single-digit day))
1456-10-05 (MMDYYYY (US, single-digit day))
1456-05-10 (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 1,051,456 and was likely granted around 1912.

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