Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020800, here are decompositions:

3 + 1020797 = 1020800
43 + 1020757 = 1020800
181 + 1020619 = 1020800
211 + 1020589 = 1020800
271 + 1020529 = 1020800
283 + 1020517 = 1020800
349 + 1020451 = 1020800
421 + 1020379 = 1020800

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 0800 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0800-02-01 (DMMYYYY (Euro, single-digit day))
0800-10-02 (MMDYYYY (US, single-digit day))
0800-02-10 (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 1,020,800 and was likely granted around 1911.

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