Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030840, here are decompositions:

  • 17 + 1030823 = 1030840
  • 23 + 1030817 = 1030840
  • 29 + 1030811 = 1030840
  • 47 + 1030793 = 1030840
  • 53 + 1030787 = 1030840
  • 89 + 1030751 = 1030840
  • 101 + 1030739 = 1030840
  • 137 + 1030703 = 1030840

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 3, 0840 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0840-03-01 (DMMYYYY (Euro, single-digit day))
  • 0840-10-03 (MMDYYYY (US, single-digit day))
  • 0840-03-10 (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 1,030,840 and was likely granted around 1912.

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