Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020190, here are decompositions:

47 + 1020143 = 1020190
53 + 1020137 = 1020190
89 + 1020101 = 1020190
113 + 1020077 = 1020190
131 + 1020059 = 1020190
167 + 1020023 = 1020190
179 + 1020011 = 1020190
263 + 1019927 = 1020190

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 0190 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0190-02-01 (DMMYYYY (Euro, single-digit day))
0190-10-02 (MMDYYYY (US, single-digit day))
0190-02-10 (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 1,020,190 and was likely granted around 1911.

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