Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026400, here are decompositions:

  • 17 + 1026383 = 1026400
  • 29 + 1026371 = 1026400
  • 41 + 1026359 = 1026400
  • 101 + 1026299 = 1026400
  • 107 + 1026293 = 1026400
  • 149 + 1026251 = 1026400
  • 173 + 1026227 = 1026400
  • 233 + 1026167 = 1026400

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 6400 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 6400-02-01 (DMMYYYY (Euro, single-digit day))
  • 6400-10-02 (MMDYYYY (US, single-digit day))
  • 6400-02-10 (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 1,026,400 and was likely granted around 1912.

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