Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051100, here are decompositions:

19 + 1051081 = 1051100
31 + 1051069 = 1051100
73 + 1051027 = 1051100
97 + 1051003 = 1051100
103 + 1050997 = 1051100
139 + 1050961 = 1051100
151 + 1050949 = 1051100
199 + 1050901 = 1051100

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 5, 1100 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1100-05-01 (DMMYYYY (Euro, single-digit day))
1100-10-05 (MMDYYYY (US, single-digit day))
1100-05-10 (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 1,051,100 and was likely granted around 1912.

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