Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021610, here are decompositions:

127 + 1021483 = 1021610
181 + 1021429 = 1021610
193 + 1021417 = 1021610
223 + 1021387 = 1021610
229 + 1021381 = 1021610
241 + 1021369 = 1021610
277 + 1021333 = 1021610
283 + 1021327 = 1021610

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 1610 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1610-02-01 (DMMYYYY (Euro, single-digit day))
1610-10-02 (MMDYYYY (US, single-digit day))
1610-02-10 (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 1,021,610 and was likely granted around 1912.

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