Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027100, here are decompositions:

3 + 1027097 = 1027100
73 + 1027027 = 1027100
97 + 1027003 = 1027100
157 + 1026943 = 1027100
241 + 1026859 = 1027100
271 + 1026829 = 1027100
367 + 1026733 = 1027100
421 + 1026679 = 1027100

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 7100 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

7100-02-01 (DMMYYYY (Euro, single-digit day))
7100-10-02 (MMDYYYY (US, single-digit day))
7100-02-10 (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 1,027,100 and was likely granted around 1912.

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