Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040800, here are decompositions:

  • 3 + 1040797 = 1040800
  • 17 + 1040783 = 1040800
  • 23 + 1040777 = 1040800
  • 29 + 1040771 = 1040800
  • 53 + 1040747 = 1040800
  • 83 + 1040717 = 1040800
  • 149 + 1040651 = 1040800
  • 269 + 1040531 = 1040800

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 0800 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0800-04-01 (DMMYYYY (Euro, single-digit day))
  • 0800-10-04 (MMDYYYY (US, single-digit day))
  • 0800-04-10 (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 1,040,800 and was likely granted around 1912.

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