Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021802, here are decompositions:

  • 3 + 1021799 = 1021802
  • 43 + 1021759 = 1021802
  • 139 + 1021663 = 1021802
  • 151 + 1021651 = 1021802
  • 181 + 1021621 = 1021802
  • 241 + 1021561 = 1021802
  • 373 + 1021429 = 1021802
  • 421 + 1021381 = 1021802

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 1802 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1802-02-01 (DMMYYYY (Euro, single-digit day))
  • 1802-10-02 (MMDYYYY (US, single-digit day))
  • 1802-02-10 (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 1,021,802 and was likely granted around 1912.

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