Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051090, here are decompositions:

11 + 1051079 = 1051090
71 + 1051019 = 1051090
83 + 1051007 = 1051090
113 + 1050977 = 1051090
191 + 1050899 = 1051090
239 + 1050851 = 1051090
317 + 1050773 = 1051090
347 + 1050743 = 1051090

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 5, 1090 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1090-05-01 (DMMYYYY (Euro, single-digit day))
1090-10-05 (MMDYYYY (US, single-digit day))
1090-05-10 (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 1,051,090 and was likely granted around 1912.

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