Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040256, here are decompositions:

  • 29 + 1040227 = 1040256
  • 37 + 1040219 = 1040256
  • 53 + 1040203 = 1040256
  • 67 + 1040189 = 1040256
  • 73 + 1040183 = 1040256
  • 89 + 1040167 = 1040256
  • 97 + 1040159 = 1040256
  • 103 + 1040153 = 1040256

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 4, 0256 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0256-04-01 (DMMYYYY (Euro, single-digit day))
  • 0256-10-04 (MMDYYYY (US, single-digit day))
  • 0256-04-10 (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 1,040,256 and was likely granted around 1912.

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