Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020028, here are decompositions:

5 + 1020023 = 1020028
17 + 1020011 = 1020028
101 + 1019927 = 1020028
167 + 1019861 = 1020028
179 + 1019849 = 1020028
227 + 1019801 = 1020028
257 + 1019771 = 1020028
281 + 1019747 = 1020028

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 0028 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0028-02-01 (DMMYYYY (Euro, single-digit day))
0028-10-02 (MMDYYYY (US, single-digit day))
0028-02-10 (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 1,020,028 and was likely granted around 1911.

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