Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057840, here are decompositions:

  • 59 + 1057781 = 1057840
  • 101 + 1057739 = 1057840
  • 137 + 1057703 = 1057840
  • 197 + 1057643 = 1057840
  • 227 + 1057613 = 1057840
  • 233 + 1057607 = 1057840
  • 263 + 1057577 = 1057840
  • 347 + 1057493 = 1057840

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 5, 7840 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7840-05-01 (DMMYYYY (Euro, single-digit day))
  • 7840-10-05 (MMDYYYY (US, single-digit day))
  • 7840-05-10 (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 1,057,840 and was likely granted around 1912.

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