Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021682, here are decompositions:

  • 19 + 1021663 = 1021682
  • 31 + 1021651 = 1021682
  • 61 + 1021621 = 1021682
  • 199 + 1021483 = 1021682
  • 241 + 1021441 = 1021682
  • 313 + 1021369 = 1021682
  • 349 + 1021333 = 1021682
  • 379 + 1021303 = 1021682

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 1682 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1682-02-01 (DMMYYYY (Euro, single-digit day))
  • 1682-10-02 (MMDYYYY (US, single-digit day))
  • 1682-02-10 (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 1,021,682 and was likely granted around 1912.

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