Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040642, here are decompositions:

  • 13 + 1040629 = 1040642
  • 61 + 1040581 = 1040642
  • 79 + 1040563 = 1040642
  • 139 + 1040503 = 1040642
  • 193 + 1040449 = 1040642
  • 223 + 1040419 = 1040642
  • 271 + 1040371 = 1040642
  • 331 + 1040311 = 1040642

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 0642 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0642-04-01 (DMMYYYY (Euro, single-digit day))
  • 0642-10-04 (MMDYYYY (US, single-digit day))
  • 0642-04-10 (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 1,040,642 and was likely granted around 1912.

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