Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021450, here are decompositions:

47 + 1021403 = 1021450
83 + 1021367 = 1021450
149 + 1021301 = 1021450
167 + 1021283 = 1021450
179 + 1021271 = 1021450
191 + 1021259 = 1021450
197 + 1021253 = 1021450
233 + 1021217 = 1021450

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 1450 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1450-02-01 (DMMYYYY (Euro, single-digit day))
1450-10-02 (MMDYYYY (US, single-digit day))
1450-02-10 (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 1,021,450 and was likely granted around 1912.

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