Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020100, here are decompositions:

23 + 1020077 = 1020100
41 + 1020059 = 1020100
89 + 1020011 = 1020100
173 + 1019927 = 1020100
197 + 1019903 = 1020100
227 + 1019873 = 1020100
239 + 1019861 = 1020100
251 + 1019849 = 1020100

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 0100 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0100-02-01 (DMMYYYY (Euro, single-digit day))
0100-10-02 (MMDYYYY (US, single-digit day))
0100-02-10 (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 1,020,100 and was likely granted around 1911.

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