Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028300, here are decompositions:

37 + 1028263 = 1028300
79 + 1028221 = 1028300
109 + 1028191 = 1028300
151 + 1028149 = 1028300
193 + 1028107 = 1028300
199 + 1028101 = 1028300
211 + 1028089 = 1028300
271 + 1028029 = 1028300

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 8300 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

8300-02-01 (DMMYYYY (Euro, single-digit day))
8300-10-02 (MMDYYYY (US, single-digit day))
8300-02-10 (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 1,028,300 and was likely granted around 1912.

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