Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042812, here are decompositions:

  • 13 + 1042799 = 1042812
  • 31 + 1042781 = 1042812
  • 53 + 1042759 = 1042812
  • 79 + 1042733 = 1042812
  • 103 + 1042709 = 1042812
  • 109 + 1042703 = 1042812
  • 131 + 1042681 = 1042812
  • 179 + 1042633 = 1042812

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 4, 2812 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2812-04-01 (DMMYYYY (Euro, single-digit day))
  • 2812-10-04 (MMDYYYY (US, single-digit day))
  • 2812-04-10 (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 1,042,812 and was likely granted around 1912.

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