Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020080, here are decompositions:

3 + 1020077 = 1020080
31 + 1020049 = 1020080
37 + 1020043 = 1020080
43 + 1020037 = 1020080
67 + 1020013 = 1020080
73 + 1020007 = 1020080
79 + 1020001 = 1020080
109 + 1019971 = 1020080

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 0080 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0080-02-01 (DMMYYYY (Euro, single-digit day))
0080-10-02 (MMDYYYY (US, single-digit day))
0080-02-10 (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 1,020,080 and was likely granted around 1911.

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