Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031986, here are decompositions:

  • 5 + 1031981 = 1031986
  • 149 + 1031837 = 1031986
  • 173 + 1031813 = 1031986
  • 227 + 1031759 = 1031986
  • 233 + 1031753 = 1031986
  • 257 + 1031729 = 1031986
  • 269 + 1031717 = 1031986
  • 317 + 1031669 = 1031986

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 3, 1986 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1986-03-01 (DMMYYYY (Euro, single-digit day))
  • 1986-10-03 (MMDYYYY (US, single-digit day))
  • 1986-03-10 (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 1,031,986 and was likely granted around 1912.

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