Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031386, here are decompositions:

  • 29 + 1031357 = 1031386
  • 107 + 1031279 = 1031386
  • 197 + 1031189 = 1031386
  • 269 + 1031117 = 1031386
  • 383 + 1031003 = 1031386
  • 467 + 1030919 = 1031386
  • 563 + 1030823 = 1031386
  • 569 + 1030817 = 1031386

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 3, 1386 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1386-03-01 (DMMYYYY (Euro, single-digit day))
  • 1386-10-03 (MMDYYYY (US, single-digit day))
  • 1386-03-10 (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 1,031,386 and was likely granted around 1912.

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