Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021436, here are decompositions:

  • 7 + 1021429 = 1021436
  • 19 + 1021417 = 1021436
  • 67 + 1021369 = 1021436
  • 103 + 1021333 = 1021436
  • 109 + 1021327 = 1021436
  • 139 + 1021297 = 1021436
  • 193 + 1021243 = 1021436
  • 277 + 1021159 = 1021436

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 1436 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1436-02-01 (DMMYYYY (Euro, single-digit day))
  • 1436-10-02 (MMDYYYY (US, single-digit day))
  • 1436-02-10 (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 1,021,436 and was likely granted around 1912.

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