Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022678, here are decompositions:

  • 67 + 1022611 = 1022678
  • 211 + 1022467 = 1022678
  • 229 + 1022449 = 1022678
  • 337 + 1022341 = 1022678
  • 487 + 1022191 = 1022678
  • 499 + 1022179 = 1022678
  • 541 + 1022137 = 1022678
  • 607 + 1022071 = 1022678

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 2678 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2678-02-01 (DMMYYYY (Euro, single-digit day))
  • 2678-10-02 (MMDYYYY (US, single-digit day))
  • 2678-02-10 (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 1,022,678 and was likely granted around 1912.

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