Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028408, here are decompositions:

  • 19 + 1028389 = 1028408
  • 79 + 1028329 = 1028408
  • 307 + 1028101 = 1028408
  • 379 + 1028029 = 1028408
  • 397 + 1028011 = 1028408
  • 421 + 1027987 = 1028408
  • 439 + 1027969 = 1028408
  • 631 + 1027777 = 1028408

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 8408 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8408-02-01 (DMMYYYY (Euro, single-digit day))
  • 8408-10-02 (MMDYYYY (US, single-digit day))
  • 8408-02-10 (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 1,028,408 and was likely granted around 1912.

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