Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021318, here are decompositions:

  • 17 + 1021301 = 1021318
  • 29 + 1021289 = 1021318
  • 47 + 1021271 = 1021318
  • 59 + 1021259 = 1021318
  • 101 + 1021217 = 1021318
  • 191 + 1021127 = 1021318
  • 227 + 1021091 = 1021318
  • 251 + 1021067 = 1021318

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 1318 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1318-02-01 (DMMYYYY (Euro, single-digit day))
  • 1318-10-02 (MMDYYYY (US, single-digit day))
  • 1318-02-10 (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 1,021,318 and was likely granted around 1912.

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