Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042140, here are decompositions:

  • 7 + 1042133 = 1042140
  • 17 + 1042123 = 1042140
  • 19 + 1042121 = 1042140
  • 31 + 1042109 = 1042140
  • 37 + 1042103 = 1042140
  • 41 + 1042099 = 1042140
  • 53 + 1042087 = 1042140
  • 59 + 1042081 = 1042140

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 4, 2140 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2140-04-01 (DMMYYYY (Euro, single-digit day))
  • 2140-10-04 (MMDYYYY (US, single-digit day))
  • 2140-04-10 (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 1,042,140 and was likely granted around 1912.

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