Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021662, here are decompositions:

  • 11 + 1021651 = 1021662
  • 41 + 1021621 = 1021662
  • 101 + 1021561 = 1021662
  • 179 + 1021483 = 1021662
  • 199 + 1021463 = 1021662
  • 233 + 1021429 = 1021662
  • 281 + 1021381 = 1021662
  • 293 + 1021369 = 1021662

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 1662 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1662-02-01 (DMMYYYY (Euro, single-digit day))
  • 1662-10-02 (MMDYYYY (US, single-digit day))
  • 1662-02-10 (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 1,021,662 and was likely granted around 1912.

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