Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026872, here are decompositions:

  • 13 + 1026859 = 1026872
  • 19 + 1026853 = 1026872
  • 43 + 1026829 = 1026872
  • 61 + 1026811 = 1026872
  • 73 + 1026799 = 1026872
  • 139 + 1026733 = 1026872
  • 163 + 1026709 = 1026872
  • 193 + 1026679 = 1026872

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 6872 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 6872-02-01 (DMMYYYY (Euro, single-digit day))
  • 6872-10-02 (MMDYYYY (US, single-digit day))
  • 6872-02-10 (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 1,026,872 and was likely granted around 1912.

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