Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025500, here are decompositions:

  • 17 + 1025483 = 1025500
  • 23 + 1025477 = 1025500
  • 41 + 1025459 = 1025500
  • 83 + 1025417 = 1025500
  • 107 + 1025393 = 1025500
  • 149 + 1025351 = 1025500
  • 167 + 1025333 = 1025500
  • 173 + 1025327 = 1025500

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 5500 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5500-02-01 (DMMYYYY (Euro, single-digit day))
  • 5500-10-02 (MMDYYYY (US, single-digit day))
  • 5500-02-10 (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 1,025,500 and was likely granted around 1912.

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