Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026540, here are decompositions:

  • 19 + 1026521 = 1026540
  • 59 + 1026481 = 1026540
  • 61 + 1026479 = 1026540
  • 83 + 1026457 = 1026540
  • 101 + 1026439 = 1026540
  • 113 + 1026427 = 1026540
  • 127 + 1026413 = 1026540
  • 139 + 1026401 = 1026540

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 6540 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 6540-02-01 (DMMYYYY (Euro, single-digit day))
  • 6540-10-02 (MMDYYYY (US, single-digit day))
  • 6540-02-10 (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 1,026,540 and was likely granted around 1912.

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