Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021396, here are decompositions:

  • 23 + 1021373 = 1021396
  • 29 + 1021367 = 1021396
  • 107 + 1021289 = 1021396
  • 113 + 1021283 = 1021396
  • 137 + 1021259 = 1021396
  • 179 + 1021217 = 1021396
  • 197 + 1021199 = 1021396
  • 239 + 1021157 = 1021396

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 1396 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1396-02-01 (DMMYYYY (Euro, single-digit day))
  • 1396-10-02 (MMDYYYY (US, single-digit day))
  • 1396-02-10 (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 1,021,396 and was likely granted around 1912.

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