Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040890, here are decompositions:

  • 17 + 1040873 = 1040890
  • 29 + 1040861 = 1040890
  • 83 + 1040807 = 1040890
  • 107 + 1040783 = 1040890
  • 113 + 1040777 = 1040890
  • 173 + 1040717 = 1040890
  • 233 + 1040657 = 1040890
  • 239 + 1040651 = 1040890

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 4, 0890 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0890-04-01 (DMMYYYY (Euro, single-digit day))
  • 0890-10-04 (MMDYYYY (US, single-digit day))
  • 0890-04-10 (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 1,040,890 and was likely granted around 1912.

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