Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021882, here are decompositions:

  • 3 + 1021879 = 1021882
  • 83 + 1021799 = 1021882
  • 89 + 1021793 = 1021882
  • 311 + 1021571 = 1021882
  • 419 + 1021463 = 1021882
  • 479 + 1021403 = 1021882
  • 509 + 1021373 = 1021882
  • 593 + 1021289 = 1021882

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 1882 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1882-02-01 (DMMYYYY (Euro, single-digit day))
  • 1882-10-02 (MMDYYYY (US, single-digit day))
  • 1882-02-10 (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 1,021,882 and was likely granted around 1912.

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