Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040818, here are decompositions:

  • 5 + 1040813 = 1040818
  • 11 + 1040807 = 1040818
  • 41 + 1040777 = 1040818
  • 47 + 1040771 = 1040818
  • 71 + 1040747 = 1040818
  • 101 + 1040717 = 1040818
  • 167 + 1040651 = 1040818
  • 239 + 1040579 = 1040818

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 0818 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0818-04-01 (DMMYYYY (Euro, single-digit day))
  • 0818-10-04 (MMDYYYY (US, single-digit day))
  • 0818-04-10 (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 1,040,818 and was likely granted around 1912.

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