Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022800, here are decompositions:

3 + 1022797 = 1022800
71 + 1022729 = 1022800
167 + 1022633 = 1022800
227 + 1022573 = 1022800
269 + 1022531 = 1022800
281 + 1022519 = 1022800
293 + 1022507 = 1022800
419 + 1022381 = 1022800

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 2800 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

2800-02-01 (DMMYYYY (Euro, single-digit day))
2800-10-02 (MMDYYYY (US, single-digit day))
2800-02-10 (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 1,022,800 and was likely granted around 1912.

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