Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020160, here are decompositions:

3 + 1020157 = 1020160
17 + 1020143 = 1020160
23 + 1020137 = 1020160
47 + 1020113 = 1020160
59 + 1020101 = 1020160
83 + 1020077 = 1020160
101 + 1020059 = 1020160
137 + 1020023 = 1020160

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 0160 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0160-02-01 (DMMYYYY (Euro, single-digit day))
0160-10-02 (MMDYYYY (US, single-digit day))
0160-02-10 (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 1,020,160 and was likely granted around 1911.

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