Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042806, here are decompositions:

  • 7 + 1042799 = 1042806
  • 47 + 1042759 = 1042806
  • 73 + 1042733 = 1042806
  • 97 + 1042709 = 1042806
  • 103 + 1042703 = 1042806
  • 113 + 1042693 = 1042806
  • 173 + 1042633 = 1042806
  • 197 + 1042609 = 1042806

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 4, 2806 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2806-04-01 (DMMYYYY (Euro, single-digit day))
  • 2806-10-04 (MMDYYYY (US, single-digit day))
  • 2806-04-10 (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 1,042,806 and was likely granted around 1912.

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