Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042836, here are decompositions:

  • 7 + 1042829 = 1042836
  • 17 + 1042819 = 1042836
  • 37 + 1042799 = 1042836
  • 103 + 1042733 = 1042836
  • 127 + 1042709 = 1042836
  • 149 + 1042687 = 1042836
  • 227 + 1042609 = 1042836
  • 229 + 1042607 = 1042836

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 4, 2836 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2836-04-01 (DMMYYYY (Euro, single-digit day))
  • 2836-10-04 (MMDYYYY (US, single-digit day))
  • 2836-04-10 (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 1,042,836 and was likely granted around 1912.

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