Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042208, here are decompositions:

  • 67 + 1042141 = 1042208
  • 109 + 1042099 = 1042208
  • 127 + 1042081 = 1042208
  • 367 + 1041841 = 1042208
  • 379 + 1041829 = 1042208
  • 421 + 1041787 = 1042208
  • 631 + 1041577 = 1042208
  • 691 + 1041517 = 1042208

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 4, 2208 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2208-04-01 (DMMYYYY (Euro, single-digit day))
  • 2208-10-04 (MMDYYYY (US, single-digit day))
  • 2208-04-10 (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 1,042,208 and was likely granted around 1912.

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