Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019170, here are decompositions:

41 + 1019129 = 1019170
101 + 1019069 = 1019170
137 + 1019033 = 1019170
233 + 1018937 = 1019170
239 + 1018931 = 1019170
263 + 1018907 = 1019170
281 + 1018889 = 1019170
311 + 1018859 = 1019170

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 9170 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

9170-10-01 (MMDYYYY (US, single-digit day))
9170-01-10 (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 1,019,170 and was likely granted around 1911.

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